Q. A reaction having equal energies of activation for forward and reverse reactions has
A) ΔS = 0
B) ΔG = 0
C) ΔH = 0
D) ΔH = ΔG = ΔS = 0
Explanation
[Solution from source] ΔH = Ea(forward) − Ea(reverse). If the two activation energies are equal, ΔH = 0. ΔG and ΔS need not be zero, since they also depend on entropy changes. Answer (3).
