The enthalpy changes for the following reactions were measured as follows:
CH4 (g) +2 O2 (g) → CO₂ (g) + 2 H₂O (g)
4,H°= -802.4 kJ/mol
CH3OH (g) + 3/2 O₂ (g) → CO₂ (g) + 2 H₂O (g) 4,H° = -676 kJ/mol
Use these values and Hess's law to determine the enthalpy change for the reaction:
CH4 (g) + O2 (g) → CH3OH (g)
