Theoretical enthalpy of methanol
WebbThe first fuel used was methanol. Methanol is a transparent, colourless liquid with a molar mass of 32 g/mol. Methanol has a low viscosity, a density of 792 kg/m 3 , a boiling point of 64, a melting point of -97, a vapour pressure of 13, and a molar enthalpy of combustion of -727 kJ/mol (National Center for Biotechnology Information., n). WebbThe enthalpy of combustion of methanol can be determined theoretically or experimentally. CH3OH(l) + 1O2(g) → CO2(g) + 2H2O(g) (a) Using the information from Table 10 of the Data Booklet, determine the theoretical enthalpy of combustion of methanol. (3)
