Vedclass · Answer

(A) The general unit for the rate constant of a reaction of order $n$ is $(mol \, L^{-1})^{1-n} \, sec^{-1}$.For a first order reaction $(n = 1)$,the unit is $(mol \, L^{-1})^{1-1} \, sec^{-1} = sec^{-1}$.For a zero order reaction $(n = 0)$,the unit is $(mol \, L^{-1})^{1-0} \, sec^{-1} = mol \, L^{-1} \, sec^{-1}$,which is equivalent to $M \, sec^{-1}$ since $M = mol \, L^{-1}$.Therefore,the units are $sec^{-1}$ and $M \, sec^{-1}$ respectively.
