(C) The general unit of the rate constant $k$ for a reaction of order $n$ is given by the formula: $(mol \ L^{-1})^{1-n} \ s^{-1}$.Given the unit is $mol^{-2} \ L^{2} \ s^{-1}$,we can equate the powers of concentration:$(mol \ L^{-1})^{1-n} = mol^{-2} \ L^{2}$.Comparing the powers of $mol$:$1-n = -2$.Solving for $n$:$n = 1 + 2 = 3$.Therefore,the order of the reaction is $3$.
