Question

Determine $Δ H / k J$ for the following reaction using the listed enthalpies of reaction:
$4 C O (g) + 8 H_{2} (g) ⟶ 3 C H_{4} (g) + C O_{2} (g) + 2 H_{2} O (l)$

$C (g r a p h i t e) + 1 / 2 O_{2} (g) ⟶ C O (g); Δ H / k J = - 110.5 k J$

$C O (g) + 1 / 2 O_{2} (g) ⟶ C O_{2} (g); Δ H / k J = - 282.9 k J$

$H_{2} (g) + 1 / 2 O_{2} (g) ⟶ H_{2} O (l); Δ H / k J = - 285.8 k J$

$C (g r a p h i t e) + 2 H_{2} (g) ⟶ C H_{4} (g); Δ H / k J = - 74.8 k J$
