Methane gas (CH4) enters a heat treatment furnace operating in steady state at 25\deg C and 1 atm pressure and reacts with 140% theoretical air of the same temperature and pressure. Combustion products come out at 1 atm pressure and 427\deg C temperatur. Determine; a) The balanced reaction equation for 1 kmol of CH4 b) Air fuel ratio at molar and mass base (Kmol-air/Kmol - Methane and kg - air/kg - methane) c) Heat transfer amount for this reaction, in kJ/kmol - CH 4
