(B) The unit of the rate constant $k$ is given as $mol \ L^{-1} \ s^{-1}$.For a reaction of order $n$,the unit of rate constant is $(mol \ L^{-1})^{1-n} \ s^{-1}$.Comparing the units: $(mol \ L^{-1})^{1-n} \ s^{-1} = (mol \ L^{-1})^1 \ s^{-1}$.Therefore,$1 - n = 1$,which gives $n = 0$.Thus,the reaction is a zero-order reaction.
