Methane gas (CH4) enters a constant pressure reactor operating at steady state conditions at 1atm inlet pressure and 25C inlet temperature. It burns at an equivalence ratio of 1.25 . The air enters the combustor at a temperature of 500K to form an equilibrium mixture of CO2,CO,H2O,H2, and N2 at an exit temperature of 1700K gOCO(1700K)=260,711kJ/kmol,gOH2O(1700K)=152,983kJ/kmol,gCO2(1700)=396,414 kJ/kmol. (a) Determine the composition of the exiting mixture. (b) Determine the heat transfer per kmol of methane. Hint: Use the following equilibrium reaction: CO2+H2>CO+H2O
