MHT CET 2026 Chemistry question

What is the term used for the minimum kinetic energy required for the reactant molecules to undergo reaction?

(A)Potential energy
(B)Bond energy
(C)Thermal energy
(D)Activation energyCorrect

Answer: (D)

Solution

In collision theory, reacting molecules must collide with a minimum energy so that bonds can break and an activated complex can form. This minimum energy (above the average energy of the reactants) that the colliding molecules must have to react is called the activation energy,
