Given
(A) \(2 CO ( g )+ O _2( g ) \rightarrow 2 CO _2( g ) \quad \Delta H _1^\circ =-x \mathrm{~kJ mol} ^{-1}\)
(B) \(C\) (graphite) \(+ O _2( g ) \rightarrow CO _2( g ) \quad \Delta H _2^\circ =-y \mathrm{~kJ mol} ^{-1}\)

The \(\Delta H ^\circ \) for the reaction
\(C\) (graphite) \(+\frac{1}{2} O _2( g ) \rightarrow CO ( g )\) is
