Question:

The reaction

\[2 \mathrm{I}^{-}(a q)+\mathrm{S}_{2} \mathrm{O}_{8}{ }^{2-}(a q) \longrightarrow \mathrm{I}_{2}(a q)+2 \mathrm{SO}_{4}{ }^{2-}(a q)\]

was studied at \(25^{\circ} \mathrm{C}\). The following results were obtained, where

\[\text { Rate }=-\frac{d\left[\mathrm{~S}_{2} \mathrm{O}_{8}{ }^{2-}ight]}{d t}\]
