Rate of a chemical reaction:
The rate of change of concentration with time of different chemical species taking part in a chemical reaction isknown as rate of reaction w.r.t that species
\mathrm{\text { Rate }=\frac{\Delta C}{\Delta t} }
Here,
\mathrm{\Delta C= } Change in concentration of any species
\mathrm{\Delta t= } - Time change corresponding to the concentration change
\mathrm{Unit ~of~ rate =\frac{\text { Unit of } \Delta C}{\text { Unit of } \Delta t} }
Here concentration is expressed in terms of pressure. So unit of change in pressure will be atm.
Unit of rate \mathrm{=\frac{a t m}{s}=a t m ~s^{-1} }.
