In the reaction,

\(\mathrm{BrO}_{3}^{-}(\mathrm{aq})+5 \mathrm{Br}^{-}(\mathrm{aq} .)+6 \mathrm{H}^{+} \rightarrow 3 \mathrm{Br}_{2}(n)+3 \mathrm{H}_{2} \mathrm{O}(n)\)

The rate of appearance of bromine (Br₂) is related to rate of disappearance of bromide ions as following:

\(\frac{d\left[\mathrm{Br}_{2}\right]}{d t}=-\frac{3}{5} \frac{d\left[\mathrm{Br}^{-}\right]}{d t}\)
\(\frac{d\left[\mathrm{Br}_{2}\right]}{d t}=-\frac{5}{3} \frac{d\left[\mathrm{Br}^{-}\right]}{d t}\)
\(\frac{d\left[\mathrm{Br}_{2}\right]}{d t}=\frac{5}{3} \frac{d\left[\mathrm{Br}^{-}\right]}{d t}\)
\(\frac{d\left[\mathrm{Br}_{2}\right]}{d t}=\frac{3}{5} \frac{d\left[\mathrm{Br}^{-}\right]}{d t}\)
