Which description explains the role of activation energy in a chemical reaction?


A .It provides useful energy that is released in an exothermic reaction.

BIt stops the products from being formed from the intermediate state.
CIt slows down the overall chemical reaction so it does not happen too quickly.
DIt provides reactants with sufficient energy for bonds to break and reform.

Verified Answer :

DActivation energy is the energy that is required in order for a reaction to occur, i.e. break and form new bonds

Answer: The description it provides reactants with sufficient energy for bonds to break and reform best explains the role of activation energy in a chemical reaction.

Explanation:

Activation energy is defined as the minimum amount of required energy so that a chemical reaction can initiate.

As a result, it provides the reactants with certain amount of energy so that they will get the necessary amount of energy to break their bond and then  form new bonds.

Thus, we can conclude that the description it provides reactants with sufficient energy for bonds to break and reform best explains the role of activation energy in a chemical reaction.
