The reaction N ₂ O ₅ 2 NO ₂+ 1 2 O ₂ is first order in N ₂ O ₅ having rate constant 6 2 10⁻⁴ ~s ⁻¹ . What is the value of rate of reaction when concentration of N ₂ O ₅ is 1 25 ~mol ~L ⁻¹ ?
Options
- A7 75 10⁻⁴ ~mol ~L ⁻¹ ~s ⁻¹
- B8 15 10⁻⁴ ~mol ~L ⁻¹ ~s ⁻¹
- C4 96 10⁻⁴ ~mol ~L ⁻¹ ~s ⁻¹
- D2 01 10⁻⁴ ~mol ~L ⁻¹ ~s ⁻¹
Correct answer
A. 7 75 10⁻⁴ ~mol ~L ⁻¹ ~s ⁻¹
Step-by-step solution
N ₂ O ₅ 2 NO ₂+ 1 2 O ₂ For first order reaction, aligned Rate &= k [ N ₂ O ₅ ] &=6.2 10⁻⁴ ~s ⁻¹ 1.25 ~mol ~L aligned
