In collision theory of chemical reaction, represents

Correct option is B

Ans.(b)

Rate of reaction according to collision theory can be expressed as

Rate =

Where, Z_AB represents the collision frequency of the reactants, A & B and

represents the fraction of molecules with energies equal to or greater than E_a

The number of collisions per second per unit volume of the reaction mixture (A and B) is known as collision frequency Z_AB.
