(C) The rate law for the reaction is given by: $\text{Rate} = k[A]^2[B]$ Rearranging to solve for the rate constant $k$: $k = \frac{\text{Rate}}{[A]^2[B]}$ Substituting the given values: $k = \frac{1.8 \times 10^{-2} \ mol \ dm^{-3} \ s^{-1}}{(0.2 \ mol \ dm^{-3})^2 \times (0.1 \ mol \ dm^{-3})}$ $k = \frac{1.8 \times 10^{-2}}{0.04 \times 0.1} = \frac{1.8 \times 10^{-2}}{4 \times 10^{-3}} = 4.5 \ mol^{-2} \ dm^6 \ s^{-1}$
