For the reaction, 3 I _ ( aq ) ⁻+ S ₂ O _ 8( aq ) ²⁻ I _ 3( aq ) ⁻+2 SO _ 4( aq ) ²⁻ , rate of formation of SO ₄²⁻ is 0.022 ~mol dm ⁻³ sec ⁻¹ . What is rate formation of I _ 3( aq ) ⁻ ?

Options

  1. A0.022 ~mol dm ⁻³ sec ⁻¹
  2. B0.11 ~mol dm ⁻³ sec ⁻¹
  3. C0.011 ~mol dm ⁻³ sec ⁻¹
  4. D0.033 ~mol dm ⁻³ sec ⁻¹

Correct answer

C. 0.011 ~mol dm ⁻³ sec ⁻¹

Step-by-step solution

aligned & 3 I _ ( aq ) ⁻+ S ₂ O _ 8( aq ) ²⁻ I _ 3( aq ) ⁻+2 SO _ 4( aq ) ²⁻ & d [ I ₃⁻ ] dt = 1 2 d [ SO ₄²⁻ ] dt = 1 2 0.022=0.011 ~mol dm ⁻³ sec ⁻¹ aligned
