delta S total and delta G

[Clement Ng]

How are delta S total and delta G related?

[Michelle Chernyak 1J]

delta S total is the total entropy change that occurs during a reaction, while delta G is the total change in gibbs free energy that dictates if the reaction is spontaneous or not. In order to solve for delta G, we can often use delta S in the equation, delta G= deltaH -Tdelta S

Depending on the signs of delta H and delta S, the sign of delta G will be positive or negative and we can therefore determine if a reaction is spontaneous or not. To guarantee spontaneity we need delta H to be negative and delta S to be positive.
