The minimum energy that two molecules should possess so that their collisions result in a chemical reaction is called energy.

Open in App

Solution

During collisions, the reactant molecules must attain a minimum amount of energy called threshold energy for the reaction to occur.
The collision model postulates that the required threshold energy for the reaction can be attained from the kinetic energy of the reactant molecules before the collision.
The extra amount of energy required for the chemical reaction to occur is called the activation energy. (E_a)
