the energy barrier that must be surmounted in order for the reactants to transform into products.

Explanation:

When we draw a reaction profile, there is always a hump that is found between the reactants and products. This hump is called the activation energy.

The activation energy of a reaction stands as a sort of barrier between reactants and products which must be surmounted before the reactants are converted into products.

Only reactants that possess the activation energy can be converted from reactants to products.
