Question

During the kinetic study of the reaction, 2A+B arrow C+D , following results were obtained Run [.A]./molL- 1 [.B]./molL- 1 Initial rate of formation of D/molL- 1min- 1 I 0.1 0.1 6.0× 10- 3 II 0.3 0.2 7.2× 10- 2 III 0.3 0.4 2.88× 10- 1 IV 0.4 0.1 2.40× 10- 2 Based on the above data which one of the following is correct? (A) rate=k[.A].[.B].2 (B) rate=k[.A].2[.B]. (C) rate=k[.A].[.B]. (D) rate=k[.A].2[.B].2

2A+B arrow C+D Let rate=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 Rate=K[.A].1[.B].2

$r a t e = k [A] [B]^{2}$

$r a t e = k [A]^{2} [B]$

$r a t e = k [A] [B]$

$r a t e = k [A]^{2} [B]^{2}$

$2 A + B \to C + D$

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 $R a t e = K [A]^{1} [B]^{2}$

Run	$[A] / m o l L^{- 1}$	$[B] / m o l L^{- 1}$	Initial rate of formation of $D / m o l L^{- 1} mi n^{- 1}$
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	$2.40 \times 1 0^{- 2}$

rate=k[A][B]2

rate=k[A]2[B]

rate=k[A][B]

rate=k[A]2[B]2

2A+B→C+D Let rate=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 Rate=K[A]1[B]2

$r a t e = k [A] [B]^{2}$

$r a t e = k [A]^{2} [B]$

$r a t e = k [A] [B]$

$r a t e = k [A]^{2} [B]^{2}$

$2 A + B \to C + D$

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 $R a t e = K [A]^{1} [B]^{2}$
