For the reaction $\text{A} + \text{B} \rightarrow \text{C} + \text{D}$, the initial rate for different reactions and initial concentration of reactants are given below:

S. No.	Initial Conc. [A] ($\text{mole L}^{-1}$)	Initial Conc. [B] ($\text{mole L}^{-1}$)	Initial rate ($\text{mole L}^{-1}\text{ sec}^{-1}$)
1	1·0	1·0	$2 \times 10^{-3}$
2	2·0	1·0	$4 \times 10^{-3}$
3	4·0	1·0	$8 \times 10^{-3}$
4	1·0	2·0	$2 \times 10^{-3}$
5	1·0	4·0	$2 \times 10^{-3}$
