Detailed Solution

The stability of carbon oxides is decided with the help of Ellingham diagram.
When carbon changes to $C O_{2}$ ,entropy $(Δ S)$ is very small and $(Δ G)$ hardly shows any change with increasing temperature but when carbon changes to $C O$ , $Δ S$ is positive and $Δ G$ becomes more negative with increasing temperature .Below 983K.temperature, formation of $C O_{2}$ is favored whereas, above this temperature , formation of $C O$ is more stable than $C O_{2}$ at more than 983 K temperature
