1.	What is the role of a catalyst in a catalysed reaction
Answer» LOWERS the ACTIVATION energy Increases the activation energy Affects the free energy change Affects the ENTHALPY change 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.
