(A) Let the rate law be $Rate = k[A]^x[B]^y$.From experiment $(1)$ and $(3)$:$[A]$ changes from $0.012$ to $0.024$ (doubled),while $[B]$ is constant $(0.035)$. The rate remains $0.10$. Thus,$x = 0$.From experiment $(1)$ and $(4)$:$[A]$ is constant $(0.012)$,while $[B]$ changes from $0.035$ to $0.070$ (doubled). The rate changes from $0.10$ to $0.80$ (increased by $8$ times).$2^y = 8 \implies y = 3$.Therefore,the rate law is $Rate = k[B]^3$.
