A catalyst increases the rate of reaction by lowering the activation energy and making it more likely that the reactants will have enough energy to react. A homogeneous catalyst is in the same state of matter as the reactants, and a heterogeneous catalyst is not. A catalyzed reaction could have a different rate law than the uncatalyzed reaction.

Work Step by Step

Concept explained in textbook. Definitions provided in textbook. Since the uncatalyzed reaction has a different reaction mechanism than the catalyzed reaction, the rate laws could differ.
