For a given reaction, adding a catalyst increases the rate of the reaction by (1) providing an alternate reaction pathway that has a higher activation energy (2) providing an alternate reaction pathway that has a lower activation energy (3) using the same reaction pathway and increasing the activation energy (4) using the same reaction pathway and decreasing the activation energy
(1) Answers
The answer is (2) providing an alternate reaction pathway that has a lower activation energy. The lower activation energy will lead to the increase of rate of the reaction.
