Question

During the kinetic study of the reaction, $2 A + B \to C + D$ , following results were obtained

Run	$[A] / m o l L^{- 1}$	$[B] / m o l L^{- 1}$	Initial rate of formation of $D / m o l L^{- 1} m i n^{- 1}$
I	0.1	0.1	$6.0 \times 1 0^{- 3}$
II	0.3	0.2	$7.2 \times 1 0^{- 2}$
III	0.3	0.4	$2.88 \times 1 0^{- 1}$
IV	0.4	0.1	$2.40 \times 1 0^{- 2}$

Based on the above data which one of the following is correct?

2 A + B → C + D Let r a t e = K [ A ] m [ B ] n To get m- value divide (IV) by I and on solving m = 1 Similarly, to get n devide (III) by (II) and on solving n = 2 Hence R a t e = K [ A ] 1 [ B ] 2
