(B) The rate law for the reaction is given by $r = k[A]^1[B]^1$. Given: $r = 15 \times 10^{-2} \ mol \ dm^{-3} \ sec^{-1}$,$[A] = 0.3 \ mol \ dm^{-3}$,and $[B] = 0.05 \ mol \ dm^{-3}$. Substituting the values into the rate law: $15 \times 10^{-2} = k \times (0.3) \times (0.05)$. $15 \times 10^{-2} = k \times (0.015)$. $k = \frac{15 \times 10^{-2}}{15 \times 10^{-3}} = 10 \ mol^{-1} \ dm^3 \ sec^{-1}$.
