How does a catalyst change the rate of a chemical reaction?
Lowers the activation energy of a reaction, therefore speeding the reaction up.Catalysts speed up chemical reactions. They do not change the products or reactants of the reaction, and are not used up or consumed in the reaction. Biological catalysts are called enzymes. Catalysts lower the activation energy (or energy needed to start a reaction), and cause the reaction to occur more quickly.
