Question

If ΔG = ΔH - TΔS, when is the overall free energy change (ΔG) in a reaction most likely to be negative (meaning that the reaction is exergonic)?

A. when products have lower potential energy and higher entropy than reactants
B. when products have higher potential energy and lower entropy than reactants
C. when products have lower potential energy and lower entropy than reactants
D. when products have higher potential energy and higher entropy than reactants
