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
Answer
Lowers the activation energy
Explanation
Solution
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.
