The chemical and their mole reaction can be expressed as follows CH4+2O2C3H8+5O2CH4+C3H8O22x+(0.22−x)5x Heat liberated →CO2+H2O→3CO2+4H2O=22.45=0.22 moles =22416=0.71 moles =0.71=0.13=0.13×890+0.09=316 kJ
When 5 litres of a gas mixture of methane and propane is perfectly combusted at 0∘C and 1 atmosphere, 16 litres of oxygen at the same temperature and pressure is consumed. The amount of heat released from the combustion in kJ (△Heomb (CH4) =890 kJ mol−1,ΔHcomb (C3H8)=2220 kJ mol−1)
