Question
Differentiate between rate of reaction and reaction rate constant.

Answer

S. No Rate of Reaction Reaction Rate Constant
(i) Rate of reaction is the change in concentration of a reactant or product in a unit interval of time. It is the rate of reaction when the molar concentration of each of the reactants is unity.
(ii) The rate of reaction at any instant of time depends upon the molar concentrations of the reactants at that time. The rate constant does not depend upon the concentrations of the reactants.
(iii) Its units are always mol litre–1 time–1. Its units depend upon the order of reaction.
