${C_{\left( s \right)}} + {H_2}{O_{\left( g \right)}} \rightleftharpoons C{O_{\left( g \right)}} + {H_{2\left( g \right)}}$
${{O}_{(g)}}+{{e}^{-}}=O_{(g)}^{-}\Delta {{H}^{o}}=-142\ kJ\,mo{{l}^{-1}}$
$O_{(g)}^{-}+{{e}^{-}}=O_{(g)}^{2-}\Delta {{H}^{o}}=844\ kJ\,mo{{l}^{-1}}$
$(A)$ $n =3,1=0, m =0$
$(B)$ $n =4, l =0, m =0$
$(C)$ $n =3, l =1, m =0$
$(D)$ $n =3, l =2, m =1$
The correct option for the order is :
