Which statement is usually true about the relationship between activation energy and reaction rates? low activation energy barriers result in low rates. high activation energy barriers result in low rates. low activation energy barriers result in no reaction. high activation energy barriers result in no reaction.

Option (b) is the correct answer.

Explanation:

Activation energy is defined as the minimum amount of energy present within a substance in order to carry out a chemical reaction.

Higher is the activation energy barrier for a chemical reaction slower will be the rate of reaction. This is because molecules with less amount of energy will not be able to participate in the chemical reaction.

As a result, less number of molecules are participating in the reaction. Due to which less number of collisions will be there. Hence, this will lead to decrease in rate of reaction.

Thus, we can conclude that the statement high activation energy barriers result in low rates, is usually true about the relationship between activation energy and reaction rates.
