Options
- A0.022 ~mol dm ⁻³ ~s ⁻¹
- B0.044 ~mol dm ⁻³ ~s ⁻¹
- C0.066 ~mol dm ⁻³ ~s ⁻¹
- D0.088 ~mol dm ⁻³ ~s ⁻¹
Correct answer
C. 0.066 ~mol dm ⁻³ ~s ⁻¹
Step-by-step solution
3 I _ (aq) ⁻+ S ₂ O _ 8( aq ) ²⁻ 2 SO _ 4( aq ) ²⁻+ I _ 3( aq ) ⁻ Rate of reaction =- 1 3 ~d [ I ⁻ ] dt =- d [ ~S ₂ O ₈²⁻ ] dt = 1 ~d [ SO ₄²⁻ ] 2 = d [ I ₃⁺ ] dt Rate of consumption of I ⁻=- 1 3 ~d [ I ⁻ ] dt = 1 ~d [ SO ₄^2 ] 2 = 3 0.044 2 =0.066 ~mol dm ⁻³ ~s ⁻¹
