(D) The rate law expression is given by $	ext{Rate} = k[A]^\alpha[B]^\beta$.From entry $1$ and $2$,$[A]$ is constant. Taking the ratio:$\frac{4 	imes 10^{-2}}{2 	imes 10^{-2}} = \frac{k[0.02]^\alpha[0.04]^\beta}{k[0.02]^\alpha[0.02]^\beta}$$2 = [2]^\beta \Rightarrow \beta = 1$.From entry $2$ and $3$,$[B]$ is constant. Taking the ratio:$\frac{8 	imes 10^{-2}}{4 	imes 10^{-2}} = \frac{k[0.04]^\alpha[0.04]^\beta}{k[0.02]^\alpha[0.04]^\beta}$$2 = [2]^\alpha \Rightarrow \alpha = 1$.Substituting $\alpha = 1$ and $\beta = 1$ into entry $1$:$2 	imes 10^{-2} = k[0.02]^1[0.02]^1$$k = \frac{2 	imes 10^{-2}}{4 	imes 10^{-4}} = \frac{200}{4} = 50 	ext{ } M^{-1}s^{-1}$.

Entry	$[A]$ in $M$	$[B]$ in $M$	Initial rate $(M/s)$
$1$	$0.02$	$0.02$	$2 \times 10^{-2}$
$2$	$0.02$	$0.04$	$4 \times 10^{-2}$
$3$	$0.04$	$0.04$	$8 \times 10^{-2}$

For a reaction $A + B \longrightarrow P$,the following data are provided. The rate constant for this reaction in standard units is:
Entry $[A]$ in $M$ $[B]$ in $M$ Initial rate $(M/s)$
$1$ $0.02$ $0.02$ $2 \times 10^{-2}$
$2$ $0.02$ $0.04$ $4 \times 10^{-2}$
$3$ $0.04$ $0.04$ $8 \times 10^{-2}$
