Determine the theoretical flame temperature that can be obtained by the combustion of methane with 25% excess air. Air and methane enter at 298K and a pressure of 1 atm. The reaction is complete. Standard heat of formation at 298 in kJ/kmol are: Methane (g) = -74520, CO (g) = -393500, Water vapor (g) = -241813.
