A gas mixture at 500C with 6.4% CO2, 0.2% O2, 40.0% CO, 50.8% H2 (% mol), (the remainder is N2) is burned with 40% dry excess air which is at 25C. The composition of the flue gas which is at 720C is 13.0% CO2, 14.3% H20, 67.6% N2, and 5.1% 02 (% mol). What was the heat transfer to or from the combustion process? AP, co, gas= - 110.54 KJ/mol AE. co2, gas= - 393.50KJ/mol A, H20, gas=-241.83 KJ/mol Cp (for all gases, liquids and vapors): 30 J/ mol.K
