Gibbs Free Energy
If deltaS is the disorder (for use of a better word) or a reaction, how is that different than delta G?

Re: Gibbs Free Energy
Delta G combines the values of delta H and delta S to fully determine whether a reaction is favorable or not.

Re: Gibbs Free Energy
Gibbs free energy is a term that defines whether a reaction will be spontaneous or not. It combines the entropy and enthalpy (delta H) to determine the favorability of a reaction.

Re: Gibbs Free Energy
DeltaG is a measure of the change in free energy of a reaction, whereas deltaS is a measure of the change in entropy. The equation deltaG = deltaH - TdeltaS uses the changes in enthalpy (deltaH) and entropy (deltaS) at constant temperature to calculate change in free energy (deltaG). A negative deltaG indicates a spontaneous reaction; a positive deltaG indicates the opposite.

Re: Gibbs Free Energy [ENDORSED]
Gibbs free energy determines the favorability of a reaction whereas S shows the change in entropy/"disorder".

Re: Gibbs Free Energy
Gibbs free energy also shows how much energy is "Free" to do nonexpansion work, whereas entropy relates to the possible number of states a system could be in.
