The minimum energy below which no reaction occur in reactant molecules is:
Correct answer: D. Activation energy of the molecules
- A. Average K. E 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 Reaction Kinetics
Reaction kinetics relates reaction rate to concentration, temperature, surface area and catalysts. Questions cover rate laws, reaction order, rate constants, activation energy and the activated complex, including how a catalyst lowers the activation energy without changing the overall energy change or equilibrium position.
