Q. Calculate the heat of formation of $CO$ using given equations
$C+O_{2} \rightarrow CO_{2};\Delta H=X$
$CO+\frac{1}{2}O_{2} \rightarrow CO_{2};\Delta H=Y$

Solution:

$C+\frac{1}{2}O_{2} \rightarrow CO$ , on substracting equation $\left(\right.\text{ii}\left.\right)$ from equation $\left(\right.i\left.\right)$ ,we get $\text{X-Y}$ .
