Question

An increase in the concentration of the reactants of a reaction leads to change in____??
(A) threshold energy
(B) collision frequency
(C) activation energy
(D) heat of reaction
​

Answer 1

(B) collision frequency

Increase in the concentration of reactant leads to the change in collision frequency. Mostly, if the concentration of one or more reactants is increased, the rate of reaction increases. This happens because a higher concentration of a reactant leads to more collisions of that reactant within a particular time period.
