Consider the reaction of peroxydisulfate ion (S2O8^2-) with iodide ion (I -) in aqueous solution.
S2O8^2-(aq) + 3 I -(aq) → 2 SO4^2-(aq) + I3^-(aq)
At a particular temperature, the rate of disappearance of S2O8^2- varies with reactant concentrations in the following manner.
Experiment--------[S2O8^2- ](M)--------[I - ](M)----------(M/s)
---------1--------------0.018------------------ 0.036-------2.6 x 10^-6
---------2--------------0.027------------------ 0.036-------3.9 x 10^-6
---------3--------------0.036------------------ 0.054-------7.8 x 10^-6
---------4--------------0.050------------------ 0.072-------1.4 x 10^-5
(a) Determine the rate law for the reaction.
(b) What is the average value of the rate constant for the disappearance of S2O8^2- based on the four sets of data?
_________M^-1s^-1
(c) What is the rate of disappearance of I - when [S2O8^2- ] = 0.021 M and [I ^- ] = 0.050 M?
_________M/s
