If a catalyst does not react with reactants how does it speed up a reaction?

Hi James,

A catalyst speeds up a reaction by providing an alternative route for the reaction with a lower activation energy. It shows up in the reaction mechanism as something added (the reactant side) although it is not actually a reactant, so it doesn't appear in the overall reaction.
