Why does every chemical reaction require a certain amount of activation energy?

a. energy is released when the reactants begin to react.

b. energy lost to the environment during the reaction must be replaced.

c. forming the activated complex requires energy,

d. the products have more potential energy than the activated complex.

e. the reactants have less potential energy than the products,

E is the correct answer because both endothermic and exothermic reactions require activation energy. the reactants have less potential energy than do the products. Energy must be input in order to raise the particles up to the higher energy level.
