Iron is obtained from iron ore by reduction with carbon monoxide. The overall reaction $i_{{?}_{?}}$

$F{e}_2{O}_3(s)+3CO(g)2Fe(s)+3C{O}_2(g)$

Calculate the enthalpy change for this reaction using the following information:$-23\mathrm{.}5$ k

$H_{\text{f}\text{o}\text{r}\text{m}\text{a}\text{t}\text{i}\text{o}\text{n}}(F{e}_2{O}_3((s)))=-825\mathrm{.}5kJmo{l}^{-1},H_{\text{f}\text{o}\text{r}\text{m}\text{a}\text{t}\text{i}\text{o}\text{n}}(CO(g))=-110\mathrm{.}5kJmo{l}^{-1},$

$H_{\text{f}\text{o}\text{r}\text{m}\text{a}\text{t}\text{i}\text{o}\text{n}}(C{O}_2((g)))=-393\mathrm{.}5kJmo{l}^{-1}.$
