(B) Let the rate law be $r = k [A]^x [B]^y$.Comparing $Exp$ $1$ and $Exp$ $2$ (where $[B]_0$ is constant):$\frac{r_2}{r_1} = \frac{k [A]_2^x [B]_2^y}{k [A]_1^x [B]_1^y} \implies \frac{0.80}{0.10} = (\frac{0.024}{0.012})^x$$8 = (2)^x \implies x = 3$.Comparing $Exp$ $1$ and $Exp$ $3$ (where $[A]_0$ is constant):$\frac{r_3}{r_1} = \frac{k [A]_3^x [B]_3^y}{k [A]_1^x [B]_1^y} \implies \frac{0.10}{0.10} = (\frac{0.070}{0.035})^y$$1 = (2)^y \implies y = 0$.Thus,the rate law is $r = k [A]^3$.
