Thermal decomposition of N 2 O 5 occurs as per the equation below : 2 N 2 O 5 → 4 NO 2 + O 2 The correct statement is

Options

  1. AO 2 production rate is four times the NO 2 production rate
  2. BO 2 production rate is the same as the rate of disappearance of N 2 O 5
  3. Crate of disappearance of N 2 O 5 is one-fourth of NO 2 production rate
  4. Drate of disappearance of N 2 O 5 is twice the O 2 production rate

Correct answer

D. rate of disappearance of N 2 O 5 is twice the O 2 production rate

Step-by-step solution

Rate of disappearance of N 2 O 5 and rate of formation of O 2 , must be in 2 : 1 ratio as per the stoichiometry of the reaction, 2 N 2 O 5 ⟶ 4 NO 2 + O 2
