What is activation energy? the energy needed to get a reaction started the energy stored in the bonds of a reaction’s enzyme the energy absorbed by the bonds that form in a reaction the heat energy given off by a reaction

Option A

Explanation:

Activation energy can be defined as the energy that is required to start a reaction. There are many factors that influence the activation energy such as temperature, pH, type of substrate.

The activation energy of a chemical reaction should be minimum so that the rest of the energy can be saved to carry forward the reaction.

Enzymes helps in lowering the activation energy by enhancing the rate of reaction.

Thus, the correct answer is option A

option a is the answer
