Question

How does a catalyst increase the rate of a reaction?

Answer 1

A Catalyst decreases the level of "Activation energy" of the reaction thus increases it's rate

Hope this helps!

Answer 2

Answer: By decreasing the activation energy.

Step-by-step explanation:

Catalyst can be defined as the substances that increases the rate of reaction by decreasing the activation energy.

In this case more energy is left for the overall reaction to take place. The catalyst can be enzymes or any chemical element that will help increasing the reaction rate.

Example: molybdenum, enzyme.
