Activation Energy is the Energy

Question

Activation energy is the energy
A) required for a chemical reaction to begin.
B) given off as the products in a chemical reaction are formed.
C) absorbed as ΔG⁰ʹ moves from negative to positive.
D) needed by an enzyme to catalyze a reaction without coenzymes.

Accepted Answer

Activation energy is the minimum amount of energy required for a chemical reaction to occur. It is the energy required to overcome the energy barrier between the reactants and products. Once the activation energy is overcome, the reaction can proceed spontaneously.
