Types of Organic Reactions
In Quiz 3 Preparation #5, the question asks "What type of reaction is shown above?" How many types of organic reactions are there? And how do we identify them? Follow-up question: Same Question, later the question asks "What is the rate limiting step?" How do you know what the ra...

Re: QUIZ 2 #11
What I did was first I used the Arrhenius equation to find the Activation Energy, E(a), which I found to be 5611 J/mol. However, I did not know how to solve for the rate constant because I do not know the value of A (rate of collisions) at 770 Kelvin...

Identifying the Anode vs. Cathode in an Equation
How are you able to know which is the agents being reduced versus oxidized qualitatively?
Example: Midterm 2016, Q8:
A standard electrochemical cell is made by placing a silver electrode into a 1.0M Ag+ solution and a cadmium electrode into a 1.0M Cd(2+) solution; what is the redox reaction?

Qualitative ways to find Entropy
How do you look at a molecule and rank their increasing standard entropy?
Example: Midterm W 2013, Q 5 B:
Arrange the following substances in order of increasing standard entropy:
CHF3 (g), CF4 (g), CH3F (g), CH2F2 (g)

Re: Quiz 1 Prep, #8
In addition to seeing that it is a trick question, you can actually derive the Temperature yourself, to prove mathematically that it is completely impossible. When I did the equation myself, I got -936K as the temperature that it needs to be, so that G will equal 0. As we know, this is impossible, a...

Re: Units of Reaction Enthalpies
In last Friday's lecture by Dr. Lavelle, it was stated that the units of reaction enthalpies depends strictly on what is being asked. For example, if the question asks for the enthalpy of a formation reaction for a single molecule, it would be kJ/mol. If it does not happen like this, it will simply ...

Re: Standard Enthalpy Question
In addition, the standard state of these diatomic gas molecules is 0, because the most stable form of any naturally occurring molecule of oxygen or bromine is in the diatomic gaseous state. As a result, to use the standard enthalpy of formation for other elements, such as Carbon, you must use the st...
