When 2.50 g of methanol undergoes complete combustion with excess oxygen 50.8 kJ of heat energy is released to the surroundings at standard conditions. Calculate the standard molar heat of combustion of methanol. 2. Write the thermochemical equation for the molar heat of combustion of methanol. Make sure you identify the physical state of the reactants and products under standard conditions. Calculate the work done at standard conditions when one mole of methanol undergoes combustion. [Use R = 8.314 E-3 kJ/mol.K]. How does the numerical value of work done compared to enthalpy change?
