I can describe what a catalyst does and explain how it affects the rate of reaction in terms of activation energy, and justify its use for a reaction based on experimental results.

A catalyst reduces the activation energy needed for a reaction.
With a catalyst present, more collisions between reactants result in the formation of product(s).
Enzymes are biological catalysts.
