Given : $\Delta H _{ f }^{\ominus}\left( Al _2 O _3\right)=-1700\,kJ\,mol ^{-1}$
$\Delta H _{ f }^\theta\left( Fe _2 O _3\right)=-840\,kJ\,mol ^{-1}$
Molar mass of $Fe , Al$ and $O$ are $56,27$ and $16\,g\,mol ^{-1}$ respectively.
$S{O_2}C{l_2}(g) \rightleftharpoons S{O_2}(g) + C{l_2}(g)$
$CO(g) + C{l_2}(g) \rightleftharpoons COC{l_2}(g)$
