How do you tell which molecule is the catalyst in a reaction?

The catalyst is something which is not a reactant or a product, it is written over the reaction arrow

Also, if you look at a reaction mechanism and a species that appears in the reactants of one elementary step appears again in the products of a following elementary step, then most likely that species will be a catalyst, as it is reformed.

Ronald's got it down! Catalysts appear on the reactant side as well as on the product side at some point in a reaction mechanism.
