Methane gas at 400 K and 1 atm enters a combustion chamber, where it is mixed with air entering at 500 K and 1 atm. The products of combustion exit at 1800 K and 1 atm. The molar analysis of the products on a dry basis is CO₂, 9.7%; CO, 0.5%; 0₂, 2.95%; and N₂, 86.85%. For operation at steady state, determine the rate of heat transfer from the combustion chamber in kJ per kmol of fuel. Neglect kinetic and potential energy effects. The average value for the specific heat Cp of methane between 298 and 400 K is 38 kJ kmol-¹K-1.
