An increse in the concentration of the reactants of a reaction leads to change in:

Options

A. Heat of reaction
B. Threshold energy
C. Collison frequency
D. Activation energy

Answer

C

Explanation

When the concentration of the reactants are raised, the reaction proceeds more quickly. This is due to an increase in the number of molecules that have the minimum required energy
Collision frequency `prop` no. of reacting molecules or atoms.
Higher the concentration of reactant molecules higher is the probability of collision and so the collision frequency
