Does adding a catalyst to a rxn mixture add energy that causes the rxn to proceed more quickly.


I answered: No, a catalyst simply lowers the activation energy by providing an alternate route to the desired product allowing the rxn to speed up.

Does that make sense? Anything I should chnage or add?
