Rate of Reaction and Reaction Rate Constant:
The following are the points of difference between the rate of reaction and reaction rate constant-
| Rate of Reaction | Reaction Rate Constant |
|---|---|
| It is measured as the rate of change of concentration of any reactant or product. | It is a constant of proportionality. |
| It depends upon the concentration of reactants. | It is independent of the concentration of reactants. |
| It changes in a reaction. | It is constant for a reaction. |
| Its unit is moles Lt-1 sec-1. | Its unit depends upon the order of the reaction. |
| It does not explain the mechanism of the reaction. | It explains the mechanism of the reaction. |
