For the reaction, H 2 + I 2 → 2 H I , the differential rate law is

Options

  1. A- d H 2 d t = - d [ I 2 ] d t = 1 2 d [ H I ] d t
  2. B- d H 2 d t = - 2 d [ I 2 ] d t = 1 2 d [ H I ] d t
  3. C- d H 2 d t = - d [ I 2 ] d t = d [ H I ] d t
  4. D- d H 2 d t = - d I 2 d t = - d [ H I ] d t

Correct answer

A. - d H 2 d t = - d [ I 2 ] d t = 1 2 d [ H I ] d t

Step-by-step solution

H 2 + I 2 → 2 H I Rate of reaction, = - d H 2 d t = - d [ I 2 ] d t = 1 2 d [ H I ] d t O r = - 2 d H 2 d t = - 2 d [ I 2 ] d t = d [ H I ] d t
