Rate of a chemical reaction:
The rate of change of concentration with time of dfferent chemical species taking part in a chemical reaction is known as rate of reaction w.r.t that species
\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
Unit of rate \mathrm{=\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{\text { atm }}{s}=atm\ s^{-1}}.
