For a reaction system that is at equilibrium,which of the following must always be true?
A)ΔH = 0
B)ΔS = 0
C)ΔG = 0
D)q = 0
E)ΔU = 0

Quizplus · Accepted Answer

At equilibrium, the Gibbs free energy change, ΔG, is equal to zero. This means that the system has reached a state of minimum free energy and is in a stable state. The other choices (ΔH, ΔS, q, and ΔU) can have non-zero values at equilibrium.
