Free Energy

[Melissa Solis 1H]

Can someone explain what a state function is again and why free energy is a state function?

[Faith Veenker 2K]

A state function only depends on start and ending states, not the path taken. Free energy is a state function because it doesn't matter how the free energy gets from one value to another, it just matters where it starts and ends up. This is different from "path" functions like heat and work. Hope this helps!

[SamanthaTolentino 3D]

A state function does not depend on the path taken to the final value/destination. Typically with state functions, we only care about the final-initial values since it is not dependent on the pathway taken.

[805295074]

State functions depend on final and initial states.

[Chris 1C]

State functions only depend on final and initial states and do not care about the pathway that it took to get there. Free energy is a state function because it satisfies that requirement.

[Aarushi Verma 2I]

A state function is where the value doesn't depend on the path taken to get there, but only the final and initial values. Free energy is a state function because we only need the final and initial values to find the change and determine whether the reaction is spontaneous.

For a state function, the path you took to get the your values does not matter so you can only take into consideration your final and initial values.

[Andy Hon 3E]

You must look at the final and initial states

[MCalcagnie_ 1D]

State functions only really focus on the initial and final states, or values. They aren't concerned with the path to get there. Free energy is a state function because we only care about and needs the initial and final states to calculate change.

[IshanModiDis2L]

The state function does not depend on the path taken to the final value or state, only the starting and ending states.

[KhanTran3K]

Hey a state function only considers the initial and final states of a reaction or value, so the "path" taken to get to a certain point doesn't matter only if the initial and final states are the same. With this, free energy is a state function in that the change in free energy for a reaction will not change no matter how we manipulate the work or path to get there. This shows us how certain reactions can be spontaneous or not.

[Stephen Min 1I]

Similar to enthalpy and entropy, free energy is a state function as it only requires the final and initial values.

[Namita Shyam 3G]

A state function is something that does not depend on the "journey" taken to go from initial to final state. Therefore, a state function is simply the difference between initial and final state. Some examples of state functions are ∆S, ∆H, and ∆G. An example of something that is not a state function is work, because work depends on the path (work is proportional to distance an object is moved, for example).

[George Hernandez 3I]

State functions are primarily focused on start and end states. The "path" taken is irrelavent.

[aashmi_agrawal_3d]

State functions only depend on the initial and final states and the path that was taken does not matter. Free energy is a state function since it is defined by other state functions H and S.

[Justin Lin 1B]

State functions are only dependent on their final and initial states, so the pathway through those states isn't important.

[Pranav Daggubati 3C]

A state function is one where the path of the change doesn't affect anything, just the start and the end.

[Brian_Wu_3B]

State functions do not depend on the path taken to get to them. State functions can be added and subtracted. Delta G is a state function because it is defined by state functions.

[Carly_Lipschitz_3H]

A state function only cares about the final and initial states and doesn't take into account the path taken. Free energy is a state function because only the final and initial values of free energy are what matters.

[Gian Boco 2G]

State functions only depend on the beginning (initial state) and the last (final) state, regardless of what happens in between.

[705383815]

Non-state functions depend on the path taken by reactants in various forms. For example, the total work exerted by a system relies on all of the work done at every point in the process. This result is not net but cumulative.

[Presley Gao 2C]

A state function is a function that does not depend on the path that is taken to get the final value. Free energy is a state function because only the initial and final values matter - the path taken does not, however.

[Gustavo_Chavez_1K]

A state function is a function that doesn't depend on the path taken to get to a final answer, as long as this function begins and ends with the same value. Free energy is a state function as the path taken to to get to the final value does not really matter.

[Taha 2D]

a state function is one in which the pathway of the energy is not important, rather where it begins and ends

[Susan Chamling 1F]

State functions do not rely on a pathway but rather the final and initial states.

[Elizabeth Kaplan 3I]

A state function is when the path taken does not matter; in other words, only the final and initial states matter. Free energy is a state function because we only need the values of the free energies of the products and reactants to determine if the reaction is spontaneous (whether the difference between the products and reactants is negative or not).

[Aliya Roserie 3I]

State functions is when u can simply solve a problem by observing the final state minus the initial state.

[sophie esherick 3H]

Like other students stated above, state functions are independent of the path taken which means that to get the value of the change of the state function you only need to subject the initial state from the final state. Free energy is a state function because it does not matter what path it took to end up in its final state (we can use the free energy values of the products and reactants to see if a reaction is spontaneous).

[Muskaan Abdul-Sattar]

For a state function, the path taken does not matter. You look solely at the final and initial values.

[Javier Perez M 1H]

In a sense, it's like looking at exothermal and endothermal graphs where we only focus on the initial and final states.

[Aria Movassaghi 1A]

State functions are path independent meaning only starting and ending values are important and this is the case with free energy.

[Jason Knight - 1F]

A state function tells us that when calculating the only values of importance are the initial and final values. The example commonly used to explain this concept was describing the pathway taken-up a hill. In summary, state functions only take into consideration the starting and ending points, and not the pathway, whether direct or indirect, that it took to get there.

[Mursall M 2A]

A state function is something that does not depend on the path taken, and only depends on the final and initial states! Free energy is a state function because no matter what path it takes, it will always be the same value, as it only focuses on final vs initial states. When something is a state function, it also means it is additive, which is why you can find the delta G of a reaction by calculating the standard delta G's of the products - standard delta G's of the reactants.

[apurva-3E]

State functions depend on the starting and end states

[Dominic Benna 2E]

State functions are independent of the path taken, so their values are only dependent on the starting and ending values.

[Shruti Kulkarni 2I]

A state function only depends on the final and initial values, it doesn't care about the "path" taken to get there. Free energy is a state function because it follows these restrictions.

[aashmi_agrawal_3d]

State functions are not affected by the path taken and only depend on the initial and final states.

[Sharon Kim 2A]

State function does not depend on the path taken. Meaning that the only thing that matters is the final and initial state of the property. That's why when you are given the standard values of Gibb's free energy, you are able to do products - reactants.

[Ethan Goode 2H]

State function only cares about the start and the end levels, not how they got there. Temperature, for example, is a state function, but work is not as more work may be done than just getting to start and end.

[Britney Tran IJ]

state functions dont depend on the path taken, just the final and initial results

[Nina Fukui 2J]

I believe state functions depend on only final and initial states so free enrgy would match that definition. Whereas other functions like work and heat do depend on the process it took to get to the final state.

[Mingzi Yang 1E]

State functions depend on both the initial and the final states. It is applicable to Gibbs free energy, enthalpy and entropy.

[Jeremy Wei 2C]

Hi, state functions are not dependent on the path taken to achieve the final state (meaning only the initial and final state are important), and free energy is an example.

[Brian Acevedo 2E]

State functions like Gibbs Free Energy (G) depend only on the initial and final values, and not on the pathway of the reaction. Because values like activation energy or free energy of intermediates (among others) do not affect the change in Gibbs Free Energy, we can assume that the Gibbs Free Energy of an overall reaction is a state function.

[Teti Omilana 1G]

state functions only focus on final and initial values, rather than the path taken.

[eve444]

State functions denote the path taken is irrelevant and only the final and initial states should be taken into account.

[Isamar Aburto Paniagua 2K]

State functions are just dependent on the initial and final states and not on the multiple paths it can take to get there.

[Jacquelyn Rivera 2I]

A state function is a process that ultimately only "cares" about the starting and ending points of it. Free energy does not require the entire process and pathway to be calculated, all that is relevant is the initial and final states.

[azurexrose]

A state function is a characteristic that means that it doesn’t matter which path is taken, the final and initial values will always been the same. Gibbs free energy is a state function because it is defined by other state functions, such as Delta H and Delta S.

[Aeson Salcedo 3L]

A state function is when the path taken does not effect the final volumes. Examples are temperature and volume.
