Question

From the following heats of combustion, CH3OH(l) + 3/2O2(g) → CO2(g) + 2H2O(l)         ΔHorxn = –726.4...

  1. From the following heats of combustion,

CH3OH(l) + 3/2O2(g) → CO2(g) + 2H2O(l)         ΔHorxn = –726.4 kJ/mol

            C(graphite) + O2(g) → CO2(g)                               ΔHorxn = –393.5 kJ/mol

            H2(g) + ½O2(g) → H2O(l)                                      ΔHorxn = –285.8 kJ/mol

           

     Calculate the enthalpy of formation of methanol (CH3OH) from its elements.

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

  1. Methanol (CH3OH) is an organic solvent and is also used as a fuel in some automobile engines. From the following data, calculate the standard enthalpy of formation of methanol:


    2CH3OH(l) + 3O2(g) → 2CO2(g) + 4H2O(l)    ΔHorxn = –1452.8 kJ/mol
