In lab you wish to explore kinetic rates of the aqueous reaction between peroxydisulfate(S2O82–) and iodide which produces sulfate and the iodine. You are able to collect the following data:
| Trial | Initial Concentration (M) | Initial Rate (M*s^-1) | |
| S2O8^2- | I- | ||
| 1 | 0.15 | 0.21 | 1.12 |
| 2 | 0.31 | 0.21 | 2.26 |
| 3 | 0.15 | 0.11 | 0.57 |
Using the data provided, what is the rate law for the above chemical reaction?
Which species in the reaction (reactants or products) would be most useful in identifying the “end” of the reaction?
