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

Options

  1. AThe rate of disappearance of B is 1/4 the rate of disappearance of A
  2. BThe rate of appearance of C is half the rate of disappearance of B
  3. CThe rate of formation of D is half the rate of consumption of A
  4. DThe rates of formation of C and D are equal

Correct answer

B. The rate of appearance of C is half the rate of disappearance of B

Step-by-step solution

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.
