Catalyst A reduces the activation energy for a reaction by 10 kJ mol - 1 at 300 K . The ratio of rate constants, k T , Catalysed k T , Uncatalysed is e x . The value of x is____[nearest integer] [Assume that the pre-exponential factor is same in both the cases. Given R = 8 . 31 J K - 1 mol - 1 ]

Correct answer

0

Step-by-step solution

Arrhenius equation for the rate constant of a reaction in terms of energy of activation is given by K = Ae - Ea RT K catalyst = Ae Ea ' RT K uncatalysed = Ae - Ea RT K catalyst K Uncatalysed = e Ea - E a ' RT = e 10 × 1000 8 . 314 × 300 = e 4
