Question

How does a catalyst increase the speed of a reaction?

A. The catalyst eliminates the activated complex stage, allowing products to form immediately.
B. The catalyst lowers the energy level of the reactants, making it easier for them to react.
C. The catalyst makes it easier for the activated complex to form, lowering the activation energy.
D. The catalyst raises the energy level of the products, making the reaction finish sooner. Reset Next

Answer 1

Answer: Option (C) is the correct answer.

Step-by-step explanation:

Catalyst are the substances which helps in increasing the rate of a chemical reaction without itself getting consumed.

A catalyst changes the path of a reaction by lowering the activation energy level so that molecules with low energy can easily participate in the reaction and thus, formation of products become fast.

Thus, we can conclude that out of the given options, a catalyst increase the speed of a reaction as the catalyst makes it easier for the activated complex to form, lowering the activation energy.
