Solution

The correct option is C $\frac{F o r m u l a w e i g h t}{6}$
In the given reaction,
$+ 5 B r O_{3}^{-} + 6 e^{-} + 6 H^{+} \to - 1 B r^{-} + 3 H_{2} O$

n-factor = Change in oxidation state of Br = 5 - (-1) = 6
so, n-factor = $6$

so, equivalent weight = $\frac{F o r m u l a w e i g h t}{n - f a c t o r}$

equivalent weight of $B r O_{3}^{-}$ = $\frac{F o r m u l a w e i g h t}{6}$
