CH3OH + 1.5O2 -> CO2 + 2H2O. Using the information from Table 10 of the Data Booklet, determine the theoretical enthalpy of combustion of methanol.

By definition, ΔH° rxn = Σ ΔH° f (products) − Σ ΔH° f (reactants).The enthalpy of combustion is the same as the enthalpy of reaction in this case. From Table 10, we can get the standard enthalpy of formation...
