Question

If a positive catalyst is added while a reaction is in progress and the energy barrier is reduced, how does it affect the rate of reaction? Rate of the reaction first decreases and then increases. Rate of the reaction first increases and then decreases. Rate of reaction increases. Rate of reaction decreases. It does not have any effect on the rate of reaction.
