$(ii)\,\, A\xrightarrow[{in\,\,absence\,\,\,of\,peroxide}]{{HBr,\,dark}}\,\,\mathop C\limits_{[Major\,product]} \, + \,\mathop D\limits_{[Minor\,product]} $

the major products $(A)$ and $(C)$ are respectively

$M{g^{2 + }} + 2{e^ - } \to Mg(s);\,\,E = - 2.37\,V$

$C{u^{2 + }} + 2{e^ - } \to Cu(s);\,\,\,E = + 0.33\,V$

$[X]$ will be :

$\left( i \right)\,2F{e_2}{O_3}\left( s \right) \to 4Fe\left( s \right) + 3{O_2}\left( g \right)$

         ${\Delta _r}{G^o} =  + 1487.0\,kJ\,mo{l^{ - 1}}$

$\left( {ii} \right)\,2CO\left( g \right) + {O_2}(g) \to 2C{O_2}\left( g \right)$

        ${\Delta _r}{G^o} =  - 514.4\,kJ\,mo{l^{ - 1}}$

Free energy change, $\Delta_rG^o$  for the reaction

$\,2F{e_2}{O_3}\left( s \right) + 6CO\left( g \right) \to 4Fe\left( s \right) + 6C{O_2}\left( g \right)$ will be .....$kJ\, mol^{-1}$
