$C{O_{2(s)}} + {H_{2(g)}} \rightleftharpoons C{O_{(s)}} + {H_2}O(g)\,;\,{K_1}$
$C{O_{2(s)}} + CO(g) \rightleftharpoons C{O_{(s)}} + C{O_2}(g)\,;\,{K_2}$
Calculate the equilibrium for the reaction
$C{O_{2(s)}} + {H_2}(g) \rightleftharpoons CO(g) + {H_2}O(g)\,$

$(A)$ Non metals have higher electronegativity than metals.
$(B)$ Non metals have lower ionisation enthalpy than metals.
$(C)$ Compounds formed between highly reactive nonmetals and highly reactive metals are generally ionic.
$(D)$ The non-metal oxides are generally basic in nature.
$(E)$ The metal oxides are generally acidic or neutral in nature.
