$\displaystyle 1$ M solution of KI reacts with excess of $\displaystyle \mathrm{H}_2 \mathrm{SO}_4$ and $\displaystyle \mathrm{KIO}_3$ solutions. According to equation $\displaystyle 5 \mathrm{I}^{-}+\mathrm{IO}_3^{-}+6 \mathrm{H}^{+} \rightarrow 3 \mathrm{I}_2+3 \mathrm{H}_2 \mathrm{O}$
Identify the correct statements :
(A)
$\displaystyle 200$ mL of KI solution reacts with $\displaystyle 0.004$ mol of $\displaystyle \mathrm{KIO}_3$
(B)
$\displaystyle 200$ mL of KI solution reacts with $\displaystyle 0.006$ mol of $\displaystyle \mathrm{H}_2 \mathrm{SO}_4$
(C)
0.$\displaystyle 5$ L of KI solution produced $\displaystyle 0.005$ mol of $\displaystyle \mathrm{I}_2$
(D)
Equivalent weight of $\displaystyle \mathrm{KIO}_3$ is equal to $\displaystyle \left(\frac{\text { Molecular weight }}{5}\right)$
