For the reaction, 4 A + B → 2 C + 2 D , the statement not correct is

Here statement in option B is incorrect while rest other statements are correct as - 1 4 d A d t = - d B d t = 1 2 d C d t = 1 2 d D d t - 1 4 d A d t = = 1 2 d C d t d C d t = 1 2 d A d t = 2 d B d t Hence the rate of appearance of C is twice the rate of disappearance of B.

For the reaction, $4 A + B \to 2 C + 2 D$ , the statement not correct is

Options:

Answer:

Solution:

Here statement in option B is incorrect while rest other statements are correct as
$- \frac{1}{4} \frac{d A}{d t} = \frac{- d B}{d t} = \frac{1}{2} \frac{d C}{d t} = \frac{1}{2} \frac{d D}{d t}$
$- \frac{1}{4} \frac{d A}{d t} = = \frac{1}{2} \frac{d C}{d t}$
$\frac{d C}{d t} = \frac{1}{2} \frac{d A}{d t} = \frac{2 d B}{d t}$
Hence the rate of appearance of C is twice the rate of disappearance of B.
