In the reaction BrO_3^-( aq )+5 Br^-( aq )+6 H^+ → 3 Br_2(l)+3 H_2 O (l) The rate of appearance of bromine ( Br_2) is related to rate of…
In the reaction
$$\mathrm{BrO}_3^{-}(\mathrm{aq})+5 \mathrm{Br}^{-}(\mathrm{aq})+6 \mathrm{H}^{+} \rightarrow 3 \mathrm{Br}_2(l)+3 \mathrm{H}_2 \mathrm{O}(l)
$$
The rate of appearance of bromine $\displaystyle \left(\mathrm{Br}_2\right)$ is related to rate of disappearance of bromide ions as following :
Official answer
(2)
$\displaystyle \frac{\mathrm{d}\left(\mathrm{Br}_2\right)}{\mathrm{dt}}=-\frac{3}{5} \frac{\mathrm{~d}\left(\mathrm{Br}^{-}\right)}{\mathrm{dt}}$
