Spontaneity
When is delta G spontaneous? Is the answer different for delta G naught to be spontaneous?

Re: Spontaneity
when delta g is negative, the reaction is spontaneous. delta g naught can only determine spontaneity if the reaction is at standard conditions. hope this helps!

Re: Spontaneity
Hi! As said by Chanel, a reaction is spontaneous when its delta G is negative, and same goes for delta G naught. The only difference being that delta G naught only applies to reactions that are at standard conditions. Hope this helps!

Re: Spontaneity
When Delta G is negative, the reaction is spontaneous. Most spontaneous reactions occur when the reaction is exothermic, meaning that Delta H is negative (Entropy is also most likely negative in this scenario).

Re: Spontaneity
When delta G = negative, then it is said to be spontaneous. These reactions also tend to be exothermic!

Re: Spontaneity
When delta g (gibbs free energy) is negative then the reaction is considered spontaneous. That is because the initial amount of energy was higher than the final amount (final-initial) and that energy was released in the reaction.

Re: Spontaneity
delta g is spontaneous when it is negative, and it essentially means that it is exothermic as well, and vice versa.

Re: Spontaneity
A spontaneous reaction occurs without the need for input of energy. Therefore with delta g is negative, energy is not required because the products are at a lower energy than the reactants.

Re: Spontaneity
Hey there!
When delta G is less than 0, the reaction is spontaneous and when delta G is greater than 0, the reaction is non-spontaneous. Non-spontaneous reactions may be coupled with spontaneous reactions in order to create an overall spontaneous reaction, given that the net delta G for both reactions is negative. When delta G is 0, the system has reached equilibrium.
I hope this helps!

Re: Spontaneity
A negative delta G indicates that a reaction will be spontaneous. Delta G naught is used under standard lab conditions and will also indicate a spontaneous reaction if it is negative. However, a reaction can be made more favorable in a certain direction by increasing or decreasing the concentrations of the products/reactants or changing temperature or pressure.

Re: Spontaneity
When delta G is negative, a reaction is spontaneous. This is because a negative delta G means that the initial state (reactants) has more free energy that the final state (products).

When delta G is negative, the reaction is spontaneous. This is the same for delta G naught. The only difference is that delta G naught can only be used and referred to at standard conditions. Hope this helps!

Re: Spontaneity
If a system is at equilibrium, ΔG = 0. If the process is spontaneous, ΔG < 0. If the process is not spontaneous as written, but is spontaneous in the reverse direction, ΔG > 0.

Re: Spontaneity
The reaction is spontaneous when its delta G is negative, regardless of whether it is delta G naught or just delta G. The only difference between delta G and delta G naught is that delta G naught is under standard conditions.

Re: Spontaneity
When delta G is negative, the reaction is spontaneous. Delta G naught refers to delta G when under standard conditions of 25 degrees Celsius and 1 atm and is still spontaneous when a negative value.

Re: Spontaneity
When Gibbs Free Energy (delta G) is negative, then the reaction is spontaneous as it is exergonic/exothermic!

Re: Spontaneity
Hi, when ΔG or ΔG⁰ is negative, the reaction is spontaneous in that direction. ΔG⁰ is just for the reaction is under standard conditions.

Re: Spontaneity
The reaction is spontaneous if delta G is negative because a negative delta G indicates that the reactants (initial state) have more free energy than the products (final state), so the reaction is exergonic. Exergonic (spontaneous) reactions can occur without the addition of energy.

When deltaG is negative, the reaction is spontaneous. When deltaG naught is negative then the reaction is spontaneous at standard conditions.
Re: Spontaneity
When delta G is negative, the forward reaction is spontaneous. Delta G naught determines spontaneity at standard conditions.

Re: Spontaneity
When delta G is negative, it is spontaneous. The other one is negative when spontaneous at Standard conditions I think.

Re: Spontaneity
For a reaction to be spontaneous, its delta G value must be negative. This can occur in endothermic and exothermic reactions (positive and negative values for delta H) and when the change in entropy (delta S) is positive or negative, depending also on the temperature. As given by the equation, delta G = delta H - T * delta S, the reaction is never spontaneous in the forward reaction when its delta H is positive and delta S is negative.

Re: Spontaneity
Spontaneous reactions have an entropy of + ∆S (meaning naturally, disorder increases in the universe). When ∆S is + then ∆G would be negative! This means that a - ∆G means a reaction is spontaneous and releases energy.

Re: Spontaneity
The reaction is spontaneous when delta G is negative, non-spontaneous when delta G is positive. This is because free energy (delta G) is the opposite of entropy/disorder (delta S), and positive delta S indicates spontaneity.

Re: Spontaneity
Hi!
When deltaG is negative, this means that the reaction is spontaneous and if deltaG is positive, this means that the reaction is not spontaneous.
Hope this helps!

Re: Spontaneity
For both delta G and delta G naught, if the values are negative, then the reaction will be spontaneous.

Re: Spontaneity
A reaction can be labeled as spontaneous when delta G is negative, and it is nonspontaneous when delta G is positive. We can determine the value for delta G from it being given to us, subtracting the delta G of reactants from products, or using the equation delta G= deltaH-T*deltaS
Re: Spontaneity
delta G is spontaneous when it is negative. Can someone explain the difference between this and delta G naught again?

Re: Spontaneity
When delta G is negative, the reaction is spontaneous. Delta G naught shows whether or not the reaction is spontaneous at standard conditions, but even if it's not, it can be made spontaneous through different concentrations of reactants and termperature.
