Consider the reaction: 2 NO ₂( ~g ) 2 NO ( g )+ O ₂( ~g ) . In the figure below, identify the curves X , Y and Z associated with the three species in the reaction-

Options

  1. AX = NO , Y = O ₂, Z = NO ₂
  2. BX = O ₂, Y = NO , Z = NO ₂
  3. CX = NO ₃, Y = NO , Z = O ₂
  4. DX = O ₂, Y = NO ₂, Z = NO

Correct answer

A. X = NO , Y = O ₂, Z = NO ₂

Step-by-step solution

r =- 1 2 d [ NO ₂ ] dt =+ 1 2 d [ NO ] dt =+ d [ O ₂ ] dt NO ₂ is reactant so ( Z ) rate of dis appearance of NO ₂= rate of formation of of NO So NO is (X)
