The reaction that has the fastest rate of reverse reaction is the one in which Ea= Ea3 = 54 kJ/mol , ΔE= ΔE3 = 8 kJ/mol (Option A).

What is activation energy?

The term activation energy refers to the minimum energy that reactants must possess in order for their collision to result in a chemical reaction.

The higher the activation energy, the faster the reverse reaction. Hence the reaction that has the fastest rate of reaction is the one in which Ea= Ea3 = 54 kJ/mol , ΔE= ΔE3 = 8 kJ/mol (Option A).
