Units of rate constant for n order reaction =(mol/L)1-ns-1=(mol dm-3)1-ns-1 On comparing these units with the given units of rate constant, we get (mol dm-3)1s-1=(mol dm-3)1-ns-1 Thus, the order of the reaction is zero.

Units of rate constant for n order reaction $= (m o l / L)^{1 - n} s^{- 1} = (m o l d m^{- 3})^{1 - n} s^{- 1}$ On comparing these units with the given units of rate constant, we get $(m o l d m^{- 3})^{1} s^{- 1} = (m o l d m^{- 3})^{1 - n} s^{- 1}$ Thus, the order of the reaction is zero.
