Solution

The correct option is C $\frac{△ [B r^{-}]}{△ t} = \frac{5}{6} \frac{△ [H^{+}]}{△ t}$
For the reaction,

$5 B r_{(a q)}^{-} + B r O_{3 (a q)}^{-} + 6_{(a q)}^{+} \to 3 B r_{2 (a q)} + 3 H_{2} O_{(l)}$

Rate of disappearance $= \frac{- 1}{5} \frac{△ [B r^{-}]}{△ t} = - \frac{△ [B r O_{3}^{-}]}{△ t} = \frac{- 1}{6} \frac{△ [H^{+}]}{△ t}$

$\frac{△ [B r^{-}]}{△ t} = \frac{5}{6} \frac{△ [H^{+}]}{△ t}$ .

Hence, the correct answer is option $C$ .
