In a reaction, the threshold energy is equal to

A

activation energy + entropy of the reaction

B

half of activation energy

C

activation energy - potential energy of the reactants

D

activation energy + potential energy of the reactants

Text Solution

Verified by Experts

The correct Answer is:
D
The minimum amount of potential energy to be possessed by reacting species to undergo a chemical reaction is called threshold energy while the minimum amount of potential energy to be acquired threugh coolision by two molecules to react is called activation energy.
The value os threshold energy as well as activation energy for a chemical reaction is primaily dependenrt on nature of reacting species.
