What is the role of a catalyst in a catalysed reaction

A

Lowers the activation energy

B

Increases the activation energy

C

Affects the free energy change

D

Affects the enthalpy change

Text Solution

Verified by Experts

The correct Answer is:
A
All substance have average energy and before the reaction occurs energy of the reactant should be higher than the average energy . We also know that catalyst lower the activation energy . Therefore, rate of reaction is increased.
