Activation energy is the energy
A) required to transform all reactants into their reactive state.
B) given off as the products in a chemical reaction are formed.
C) absorbed as ΔG⁰' moves from negative to positive.
D) needed by an enzyme to catalyze a reaction without coenzymes.

Question

Quizplus · Accepted Answer

Activation energy is the minimum amount of energy required to initiate a chemical reaction by breaking the bonds of the reactants and making them reactive. It is not related to the energy given off as products are formed, or the change in Gibbs free energy (ΔG⁰') or the need for coenzymes for enzyme catalysis.
