Question

The increase in concentration of the reactants lead to change in :

• A. $△H$
• B. Collision frequency
• C. Activation energy
• D. Equilibrium constant

Answer 1

The correct option is B Collision frequency

Collision frequency $\propto$ no. of reacting molecules or atoms

The higher the concentration of reactant molecules, the higher is the probability of collision and so the collision frequency.

Option B is correct.
