Question

Given the following thermos chemical reactions:

$X O_{2} (s) + C O (g) \to X O (s) + C O_{2} (g)$ ; $Δ H = - 20.0$ kJ

$X_{3} O_{4} (s) + C O (g) \to 3 X O (s) + C O_{2} (g)$ ; $Δ H = + 6.0$ kJ

$3 X_{2} O_{3} (s) + C O (g) \to 2 X_{3} O_{4} (s) + C O_{2} (g)$ ; $Δ H = - 12.0$ kJ

Find $Δ H$ in kJ for the reaction.

$2 X O_{2} (s) + C O (g) \to X_{2} O_{3} (s) + C O_{2} (g)$ .
