catalysts are a substances that increase the rate of reaction without being chemically changed or used up in the reaction

because it isnt used up you only need tiny amounts to catalyse large amounts of reacntants 

they work by decreasing the activation energy needed for a reaction to occur they do this by providing an alternative reaction pathway…
