Given C(s)+O 2 -> CO 2 with Delta H=-393.5 kJ/mol and CO+ tfrac12O 2 -> CO 2 with Delta H=-283.0 kJ/mol, find Delta H for C(s)+ tfrac12O 2 -> CO.

Given $C (s) + O_{2} \to C O_{2}$ with $Δ H = - 393.5$ kJ/mol and $C O + \frac{1}{2} O_{2} \to C O_{2}$ with $Δ H = - 283.0$ kJ/mol, find $Δ H$ for $C (s) + \frac{1}{2} O_{2} \to C O$ .
