Answer:
c. Minimum amount of energy for the reaction to occur
Explanation:
The "energy of activation" or "activation energy" refers to the minimum amount of energy for the reaction to occur or the minimum amount of energy needed for molecules to go through a chemical reaction. It is commonly measured in J/mole (Joules per mole).
The activation energy was termed by Svante Arrhenius, a Swedish scientist. He also developed a formula in order to show the relationship between the activation energy of the chemical reaction and its rate. He proved them to be indirectly proportional. The higher the activation energy, the lower the chemical rate.
