Experiment	[A]<br>(in $\text{mol L}^{-1}$ )	[B]<br>(in $\text{mol L}^{-1}$ )	Initial Rate of reaction<br>(in $\text{mol L}^{-1} \text{min}^{-1}$ )
(I)	0.10	0.20	$6.93 \times 10^{-3}$
(II)	0.10	0.25	$6.93 \times 10^{-3}$
(III)	0.20	0.30	$1.386 \times 10^{-2}$

The time (in minutes) required to consume half of A is:<br>&emsp;(1) 10<br>&emsp;(2) 5<br>&emsp;(3) 100<br>&emsp;(4) 1
