A. They lower the activation energy.
Catalysts increase the rate of a chemical reaction by providing an alternative reaction pathway that has a lower activation energy compared to the uncatalyzed reaction. This means that more molecules can effectively collide with sufficient energy to overcome the energy barrier, leading to an increased rate of reaction.
