C)∆S
D)∆E

∆G (change in Gibbs free energy) defines the group transfer potential that occurs upon hydrolysis. It represents the maximum amount of work that can be obtained from the reaction and determines whether the reaction is thermodynamically favorable or unfavorable. A negative ∆G indicates that the reaction is spontaneous and exergonic, while a positive ∆G indicates that the reaction is non-spontaneous and endergonic. ∆H (change in enthalpy) and ∆S (change in entropy) can also affect the energetics of a reaction, but they do not specifically define the group transfer potential. ∆E (change in internal energy) is related to work done on or by the system and is not a thermodynamic property.
