Question

CH3OH (l) + 3/2 O2 (g) → CO2 (g)  + 2 H2O (l), ΔH = -726.4 KJ/mol

C (graphite) + O2 (g)  → CO2 (g),  ΔH = - 393.5 KJ/mol

H2 (g) + ½ O2 (g)  →  H2O (l), ΔH = - 285.8 KJ/mol

Calculate the enthalpy of formation of methanol from its elements:

C (graphite)  + 2 H2 (g)  +  ½ O2 (g)   →  CH3OH (l)
