For reaction 1 2 A → 2 B rate of disappearance of A is related to rate appearance of B by the expression

Options

  1. A- d A d t = 1 2 d B d t
  2. B- d A d t = 4 d B d t
  3. C- d A d t = 1 4 d B d t
  4. D- d A d t = d B d t

Correct answer

C. - d A d t = 1 4 d B d t

Step-by-step solution

For the given chemical equation, we have - 1 V A d A d t = 1 V B d B d t i.e. - 1 1 ∕ 2 d A d t = 1 2 d B d t Hence, - d A d t = 1 4 d B d t
