Arrhenius equation gives the change in rate constant (and hence rate of reaction) with temperature. If the activation energy of the reaction is found to be equal to RT, then

Question

Correct answer: B. From the Arrhenius equation, K = A * e^(-Ea/RT). If Ea = RT, then K = A * e^(-1) = A / e = A / 2.718 ≈ 0.368 A. This means the rate constant becomes approximately 37% of the pre-exponential factor A. Therefore, correct answer is B.
