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. |
