Answer:
The activation energy of a chemical reaction is closely related to its rate. Specifically, the higher the activation energy, the slower the chemical reaction will be. This is because molecules can only complete the reaction once they have reached the top of the activation energy barrier.
Explanation: Each and every chemical reaction require some amount of activation energy to begin. The activation energy enables the reactants to move and overcome forces of repulsion. The subsequent collisions between atoms facilitates the breaking of existing bonds and the formation of new ones.
