Question

The reaction H 2 SeO 3 (aq)6I - (aq)+ 4H + (aq)$\to$2I 3 - (aq)+ 3H 2 O(l)+ Se(s)was studied at 0°C by the method of initial rates:

-The numerical value of the rate constant is

Quizplus · Accepted Answer

The rate law for the reaction is:Rate = k[HS1U1B12S1U1B0SeOS1U1B13S1U1B0][HS1U1P1+S1S1P0]The rate constant can be determined from any of the experiments. For example, using the first experiment:Rate = 1.0 F1F1F1S1F1F1F10 10S1U1P1-S1S1P0S1U1P14S1S1P0 = k[HS1U1B12S1U1B0SeOS1U1B13S1U1B0][HS1U1P1+S1S1P0]1.0 F1F1F1S1F1F1F10 10S1U1P1-S1S1P0S1U1P14S1S1P0 = k(1.0 F1F1F1S1F1F1F10 10S1U1P1-S1S1P0S1U1P14S1S1P0)k = 1.0 F1F1F1S1F1F1F10 10S1U1P1-S1S1P0S1U1P14S1S1P0k = 5.2 F1F1F1S1F1F1F10 10⁵
