2. Combustion of methane can be presented by the following reactions; CH 4 + 202 CH 4 +1.50 2 CO 2 + 2H 2 O CO+ 2H2O 100 mol/h of methane is fed to a reactor and completely burns with 50% excess air. The analysis of the flue gases indicates that the mole ratio of CO2 to CO is 3. Calculate the molar composition of the flue gases on a wet basis.
