Find the average rate of formation of NO _ 2( ~g ) , in following reaction. 2 ~N ₂ O _ 5( ~g ) 4 NO _ 2( ~g ) + O _ 2( ~g ) [- [ N ₂ O ₅ ] t ]=x ~mol dm ⁻³ ~s ⁻¹
Options
- Ax ~mol dm ⁻³ ~s ⁻¹
- Bx 2 ~mol dm ⁻³ ~s ⁻¹
- C2 x ~mol dm ⁻³ ~s ⁻¹
- D4 x ~mol dm ⁻³ ~s ⁻¹
Correct answer
C. 2 x ~mol dm ⁻³ ~s ⁻¹
Step-by-step solution
aligned & - [ N ₂ O ₅ ] t =x ~mol dm ⁻³ ~s ⁻¹ & 2 ~N ₂ O _ 5( ~g ) 4 NO _ 2( ~g ) + O _ 2( ~g ) aligned Average rate of reaction gathered =- 1 2 [ N ₂ O ₅ ] t = 1 4 [ NO ₂ ] t = [ O ₂ ] t [ NO ₂ ] t =- 4 2 [ N ₂ O ₅ ] t = 4 2 x =2 x ~mol dm ⁻³ ~s ⁻¹ gathered Average rate of formation of NO _ 2( ~g ) =2 x ~mol dm ⁻³ ~s ⁻¹ [Note: In the question, [ N ₂ O ₅ ] t is changed to - [ N ₂ O ₅ ] t to apply appropriate textual concepts.]
