(B) The rate law for the reaction $A + 2B 	o C + D$ can be written as $Rate = k[A]^x[B]^y$,where $x$ and $y$ are the orders with respect to $A$ and $B$ respectively.According to the problem,when $[A]$ is increased $9$ times,the rate increases $3$ times:$3 	imes Rate = k(9[A])^x[B]^y$$3 = 9^x \implies 3 = (3^2)^x \implies 3^1 = 3^{2x} \implies x = \frac{1}{2}$.When $[B]$ is increased $2$ times,the rate increases $2$ times:$2 	imes Rate = k[A]^x(2[B])^y$$2 = 2^y \implies y = 1$.The total order of the reaction is $x + y = \frac{1}{2} + 1 = \frac{3}{2}$.

For a chemical reaction,$A + 2B \to C + D$,the rate of reaction increases $3$ times when the concentration of $A$ only is increased $9$ times. While when the concentration of $B$ only is increased $2$ times,the rate of reaction also increases $2$ times. The order of this reaction is:
