Rate of a chemical reaction:
The rate of change of concentration with time of different chemical species taking part in a chemical reaction is known as rate of reaction w.r.t that species
\mathrm{\text { Rate }=\frac{\Delta C}{\Delta t} }
\mathrm{\Delta C= }  Change in cocentration of any species
\mathrm{\Delta t= } Time change corresponding to the concentration change
Unit of rate =\frac{\text { Unit of } \Delta C}{\text { Unit of } \Delta r}=\frac{\text { mol }}{L \cdot s}.
