(Q5) (a) Calculate the heat of combustion (AH) of methanol (CH3OH) in liquid form for complete combustion based on the given data on heat of formation (AH) (b) Write down the chemical reaction for incomplete combustion of methanol with CO and water vapour as products and hence estimate related heat released per mole of methanol consumed (c) Discuss the errors for estimating possible heat released in real fire cases based on the results in part (a) and (b) with related assumptions TABLE 1.1 Heats of Formation at 298K Chemical Name State AH (d/mol) AC (kJ/g mol) с Carbon Vapor 716.67 5072 N Nitrogen atom Cas 472.68 33.76 ° Oxygen atom Gas 24937 15.57 C₂H₂ Acetylene Gas 227.06 8.79 H Hydrogen atom Gas 218.00 218.00 °, Отопе Gas 142.67 2.97 NO Nicode Cas 90.29 3.01 CH Benzene Gas 1296 1.06 CH Benzene Liquid 49.06 0.63 כאי Ethene Cas 52.38 1.87 NH, Hydrazine Liquid 50.63 1.58 CH Hydroxyl Gas 38.00 229 radical 0, Oxyern Gas 0 ° Nj Nitrogen Gas 0 ° H₂ Hydrogen Gas ° ° C Carbon Solid 0 ° NH, Ammonia Gas -45.90 -2.70 сно Ethylene oxide Gas -51.08 -0.
