Chemistry

Propane is mixed with 20% excess air (propane air mixture isinitially at 25 Â°C and 2.0 atm) and combusted at atmosphericpressure. It is assumed that the heat transfer between the chamberand the surroundings is negligible. In addition, you may assumethat heat capacities of the gases are constant and that thereaction proceeds to 100% conversion. (30 points) a) Determine theflame temperature of the burner. b) Determine the flame temperatureif 25% of the heat generated by combustion was lost through heattransfer to the surroundings? While doing the calculations you mayassume that the heat capacities of the gases are constant. The heatcapacities of the gases of interest are shown below. Gas Heatcapacity Nitrogen 29.12 J/(molk) Oxygen 29.39 J/(molk) Propane74.92 J/(molk) Carbon dioxide 37.14 J/(molk) Water 33.57J/(mol*k)
