For the reaction 2 ~N ₂ O _ 5_ (8) 4 NO _ 2_ ( g ) + O _ 2_ (8) initial concentration of N ₂ O ₅ is 2.0 molL ⁻¹ and after 300 , it is reduced to 1.4 molL ⁻¹ . The rate of production of NO ₂ ( . in molL ⁻¹ ~min ⁻¹ ) is
Options
- A2.5 10⁻⁴
- B4 10⁻⁴
- C2.5 10⁻³
- D4 10⁻³
Correct answer
D. 4 10⁻³
Step-by-step solution
Rate of formation of NO ₂=2 rate of disappearance of N ₂ O ₅ aligned & =2 [ -(1.4-2) 300 ] & =4 10⁻³ aligned
