Chemical Kinetics

For the reaction,

\(3 \mathrm{I}_{(\mathrm{aq})}^{-}+\mathrm{S}_2 \mathrm{O}_{8(\mathrm{aq})}^{2-} \longrightarrow 2 \mathrm{SO}_{4(\mathrm{aq})}^{2-}+\mathrm{I}_{3(\mathrm{aq})}^{-}\)

rate of formation of $\mathrm{SO}_{4(\text { aq })}^{2-}$ is $0.044 \mathrm{~mol} \mathrm{dm}^{-3} \mathrm{~s}^{-1}$.

What is the rate of consumption of $\mathrm{S}_2 \mathrm{O}_{8(\mathrm{aq})}^{2-}$ ?
