Propane is burned completely with excess oxygen. The product gas contains 24.5 mole% CO2, 6.10% CO, 40.8% H2O, and 28.6% O2. (a) Calculate the percentage excess O2 fed to the furnace. (b) A student wrote the stoichiometric equation of the combustion of propane to form CO2 and CO as: 2C3H8 + 11O2 → 3CO2 + 3CO + 8H2O According to this equation, CO2 and CO should be in a ratio of 1/1 in the reaction products, but in the product gas of Part (a) they are in a ratio of 24.8/6.12. Is that result possible? (Hint: Yes.) Explain how

Question
Propane is burned completely with excess oxygen. The product gas contains 24.5 mole% CO2, 6.10% CO, 40.8% H2O, and 28.6% O2.
(a) Calculate the percentage excess O2 fed to the furnace.
(b) A student wrote the stoichiometric equation of the combustion of propane to form CO2 and CO as:
2C3H8 + 11O2 → 3CO2 + 3CO + 8H2O
According to this equation, CO2 and CO should be in a ratio of 1/1 in the reaction products, but in the product gas of Part (a) they are in a ratio of 24.8/6.12. Is that result possible? (Hint: Yes.) Explain how
