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

Options

A. Activation energy of the backward reaction is increased by 5 kJ `mol^(-1)`
B. Activation energy of the backward reaction 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

Answer

B

Explanation

Energy of backward reaction is also decreased by 5 kj `mol^(-1)` without affecting the value of `triangleH` and `k_(eq)` of the reaction
