The activation energy of a chemical reaction is the energy that:

A. Must be removed from the mixture.
B. Activates the catalyst.
C. Is the energy difference between the reactants and products.
D. Needs to be added to initiate the reaction.
E. Is released from the reactants.



Answer :

Final answer:

Activation energy is the essential energy required to initiate a chemical reaction and enable the transition from reactants to products.


Explanation:

Activation energy is the amount of energy required to start a chemical reaction. It represents the minimum energy needed to overcome the energy barrier for reactants to turn into products. Catalysts can lower this activation energy, enabling reactions to occur more efficiently and quickly.
