A catalyst lowers the activation energy ...

A catalyst lowers the activation energy from 20 kJ `mol^(-1)` to 15 kJ `mol^(-1)` of the forward direction of the reaction A `rarr` B which of the following statement regarding the reaction is correct

A

Activation energy of the backward direction is increased by 5 kJ `mol^(-1)`

B

Activation energy of the backward direction is decreased by 5 kJ `mol^(-1)`

C

Enthalpy of reaction is increased by 5 kJ `mol^(-1)`

D

Equilibrium constant of the reaction is decreased `5 kJ mol^(-1)`

Text Solution

Verified by Experts

Energy of backward reaction is also decreased by `5 kJ mol^(-1)` without affecting the value of `Delta H` and `K_(eq)` of the reaction.
