Question

Why does every chemical reaction require a certain amount of activation energy? A. Energy is released when the reactants begin to react. B. Energy lost to the environment during the reaction must be replaced. C. Forming the activated complex requires energy. D. The products have more potential energy than the activated complex. E. The reactants have less potential energy than the products.

Answer 1

Answer: Option (C) is the correct answer.

Explanation:

Activation energy is defined as the minimum amount of energy required for a chemical reaction to start.

An activated complex is also known as transition state where bonds between the reactants are breaking and bonds between the products are forming.

For a chemical reaction, activation energy is required to result in the formation of activated complex.

Therefore, we can conclude that every chemical reaction require a certain amount of activation energy because forming the activated complex requires energy.
