What is Gibbs free energy?
The change in Gibbs free energy, ΔG, is a convenient way to determine whether a reaction is spontaneous or feasible
How to determine the temperature at which a reaction is feasible
A spontaneous or feasible process must be accompanied by a positive change in total entropy (entropy of the universe). Whether
