Solution

The correct option is C $(y - x) k J / m o l$
$C (s) + O_{2} (g) \to C O_{2} (g) + x k J . . . (1)$
$C O (g) + \frac{1}{2} O_{2} (g) \to C O_{2} (g) + y k J . . . (2)$
$(1) - (2) C (s) + \frac{1}{2} O_{2} \to C O (g) + (x - y) (k J)$
Heat of formation of CO(g) $= E H_{f} P r o d u c t s - E H_{f} R e a c t a n t s$
$= y - x$
