For the reaction

2A+B\rightarrow\text{products}

, the following initial rates were obtained at various initial concentrations:

$[A]$	$[B]$	Rate $\left(\text{mol L}^{-1}\text{ s}^{-1}\right)$
$0.1\text{ M}$	$0.2\text{ M}$	$0.46$
$0.2\text{ M}$	$0.2\text{ M}$	$1.84$
$0.2\text{ M}$	$0.1\text{ M}$	$0.92$

The rate law for the reaction is (1)

\text{Rate}=k[A]^2[B]^0

(2)

\text{Rate}=k[A][B]

(3)

\text{Rate}=k[A]^2[B]

(4)

\text{Rate}=k[A][B]^2
