Check the feasibility of the given reactions and mark the ones that are not feasible.
\mathrm{(I)\ 2 \mathrm{KI}+\mathrm{Br}_2 \longrightarrow 2 \mathrm{KBr}+\mathrm{I}_2}
\\(II)\ 2 \mathrm{KBr}+\mathrm{I}_2 \rightarrow 2 \mathrm{KI}+\mathrm{Br}_2\\ (III)\ 2 \mathrm{KBr}+\mathrm{Cl}_2 \rightarrow 2 \mathrm{KCl}+\mathrm{Or}_2\\ \mathrm{(IV)}\ 2 \mathrm{H}_2 \mathrm{O}+2 \mathrm{~F}_2 \rightarrow 4 \mathrm{HF}+\mathrm{O}_2
\\(V)\ \mathrm{Li}+\mathrm{H}_2 \mathrm{O} \rightarrow \mathrm{LiOH}+\mathrm{H}_2\\ (VI)\ \mathrm{Ag}+\mathrm{H}_2 \mathrm{O} \rightarrow \mathrm{AgOH}+\mathrm{H}_2

\mathrm{Br} is not oxidised by \mathrm{I_2} as \mathrm{E^{\circ}\ of\ I_2} is higher as compund to that of \mathrm{B r}. \mathrm{Ag} can't displace \mathrm{H} as it is placed below Hydrogen in the reactivity series.
