Reactants capable of interacting to form products in a chemical reaction must first overcome a thermodynamic barrier known as the reaction's
A) entropy.
B) activation energy.
C) endothermic level.
D) equilibrium point.
E) free-energy content.

Question

Quizplus · Accepted Answer

The activation energy is the energy required for a chemical reaction to occur. Reactants must first overcome this thermodynamic barrier before they can interact to form products.

Note: Entropy, endothermic level, equilibrium point, and free-energy content are all important concepts in thermodynamics, but they do not specifically relate to the initial barrier that must be overcome for a chemical reaction to occur.
