What does a catalyst do in a reaction?
The overall energy change stays the same because the reactant and product energy levels are unchanged.
A catalyst increases the rate of a reaction without being used up.
On a reaction profile, the catalysed pathway has a lower peak than the uncatalysed pathway.
Enzymes are used in industry, including making foods and washing powders.
