The minimum energy below which no reaction occur in reactant molecules is:
Correct answer: D. Activation Energy of the molecules
- A. Average Kinetic Energy of the molecules
- B. Potential Energy of the molecules
- C. Free Energy of the molecules
- D. Activation Energy of the molecules
Explanation
Activation energy is the minimum energy that the reactants must have to be converted into products. It can also be described in terms of energy which activate reactants to start a chemical reaction.

About Activation Energy and Activated Complex
Activation energy is the minimum energy reactant particles need to form the activated complex, or transition state, during a reaction. Energy profile diagrams show the forward and reverse activation energies, while catalysts provide an alternative pathway with lower activation energy without changing the reaction enthalpy.
