A) the energy lost or gained in a reaction.
B) the energy required for an endergonic reaction.
C) the energy required to bring molecules into a position where they can interact.
D) required to convert an endergonic reaction to an exergonic reaction.

Accepted Answer

Activation energy is the energy required to bring molecules into a position where they can interact, creating a transition state that promotes the formation of a product or an intermediate in a chemical reaction.
