Find the average rate of formation O _ 2( ~g ) in the following reaction. aligned & 2 NO _ 2( ~g ) 2 NO _ ( g ) + O _ 2( ~g ) & [- [ NO ] t ]= x moldm ⁻³ ~s ⁻¹ aligned

Options

  1. Ax 2 ~mol dm ⁻³ ~s ⁻¹
  2. Bx mol dm ⁻³ ~s ⁻¹
  3. C2 mol dm ⁻³ ~s ⁻¹
  4. D4 mol dm ⁻³ ~s ⁻¹

Correct answer

A. x 2 ~mol dm ⁻³ ~s ⁻¹

Step-by-step solution

Average rate of reaction =- 1 2 [ NO ₂ ] t = 1 2 [ NO ₂ ] t = [ O ₂ ] t Rate of formation of O ₂= [ O ₂ ] t aligned & = 1 2 - [ NO ₂ ] t & = 1 2 x = x 2 ~mol dm ⁻³ ~s ⁻¹ aligned
