For the reaction 2 SO ₂+ O ₂ 2 SO ₃ , the rate of disappearance of O ₂ is 2 10⁻⁴ ~mol ~L ⁻¹ s ⁻¹ . The rate appearance of SO ₃ is
Options
- A2 10⁻⁴ ~mol ~L ⁻¹ ~s ⁻¹
- B4 10⁻⁴ ~mol ~L ⁻¹ ~s ⁻¹
- C1 10⁻¹ ~mol ~L ⁻¹ ~s ⁻¹
- D6 10⁻⁴ ~mol ~L ⁻¹ ~s ⁻¹
Correct answer
B. 4 10⁻⁴ ~mol ~L ⁻¹ ~s ⁻¹
Step-by-step solution
2 SO ₂+ O ₂ 2 SO ₃ Rate of reaction =- 1 2 d [ SO ₂ ] d t =- d [ O ₂ ] dt = 1 2 d [ SO ₃ ] d t Rate of appearance of SO ₃ , aligned d [ SO ₃ ] d t & =2 [ -d [ O ₂ ] d t ]=2 (2 10⁻⁴ ) & =4 10⁻⁴ ~mol ~L ⁻¹ ~s ⁻¹ aligned
