Question

Why does a catalyst cause a reaction to proceed faster?

a. The activation energy is lowered only.
b. There are more collisions per second and the collisions are of greater energy.
c. There are more collisions per second only.
d. The collisions occur with greater energy only.

Answer 1

A

Step-by-step explanation:

I am going to use the example of Enzymes, which are simply catalysts, but of biological origin. These enzymes would provide another path, which has a lower activation energy. In this way, catalysts reduce the amount of energy required to start the reaction.
