Options
- A1.7 ~mol ~L ⁻¹
- B3.0 ~mol ~L ⁻¹
- C3.4 ~mol ~L ⁻¹
- D5.1 ~mol ~L ⁻¹
Correct answer
B. 3.0 ~mol ~L ⁻¹
Step-by-step solution
2 ~N ₂ O _ 5( ~g ) 4 NO _ 2( ~g ) + O _ 2( ~g ) It is a first order reaction, array ll & Rate = k [ ~N ₂ O ₅ ] & 1.02 10⁻⁴=3.4 10⁻⁵ [ ~N ₂ O ₅ ] & [ N ₂ O ₅ ]= 1.02 10⁻⁴ 3.4 10⁻⁵ =3.0 ~mol ~L ⁻¹ array
