Options

  1. A- d N H 3 d t = - d O 2 d t = - d N O d t = - d [ H 2 O ] d t
  2. Bd N H 3 d t = d O 2 d t = - 1 4 d N O d t = - 1 6 d [ H 2 O ] d t
  3. C1 4 d N H 3 d t = 1 5 d O 2 d t = 1 4 d N O d t = 1 6 d [ H 2 O ] d t
  4. D- 1 4 d N H 3 d t = - 1 5 d O 2 d t = 1 4 d N O d t = 1 6 d [ H 2 O ] d t

Correct answer

D. - 1 4 d N H 3 d t = - 1 5 d O 2 d t = 1 4 d N O d t = 1 6 d [ H 2 O ] d t

Step-by-step solution

The differential rate law for the reaction, 4 N H 3 g + 5 O 2 g → 4 N O g + 6 H 2 O ( g ) is R a t e = - 1 4 d N H 3 d t = - 1 5 d O 2 d t = + 1 4 d N O d t = + 1 6 d [ H 2 O ] d t
