Which of the following best describes the result of using a catalyst in a chemical reaction?
a. the yield of product is increased.
b. a more desirable product is often formed.
c. a greater amount of heat energy is released by the reaction.
d. the reaction is completed in a shorter amount of time.

Option (D) is the correct answer.

Explanation:

A catalyst is defined as the substance that lowers the activation energy of a chemical reaction without itself getting consumed so that there will be increase in rate of reaction.

As catalyst lowers the activation energy so, reactant molecules with lower energy also participates in the reaction. Hence, morr collisions occur due to which there is rapid formation of products.

Thus, we can conclude that statement the reaction is completed in a shorter amount of time, best describes the result of using a catalyst in a chemical reaction.
