Methane is burned with air in a continuous steady-state combustion reactor to yield a mixture of carbon monoxide, carbon dioxide, and water. The reactions taking place are: CH4 +O2 → CO+ 2H2O CH4 + 202 → CO2 + 2H2O The feed to the reactor contains 7.80 mole% CH4, 19.4% O2, and 72.8% N2. The percentage conversion of methane is 90.0%, and the gas leaving the reactor contains 8 mol CO2/mol CO. Carry out a degree-of-freedom analysis on the process. Then calculate the molar composition of the product stream using molecular species balances, atomic species balances, and extents of reaction.

Methane is burned with air in a continuous steady-state combustion reactor to yield a mixture
of carbon monoxide, carbon dioxide, and water. The reactions taking place are:
CH4 +O2 →
CÓ + 2H2O
CH4 + 202
CO2 + 2H2O
The feed to the reactor contains 7.80 mole% CH4, 19.4% 02, and 72.8% N2. The percentage
conversion of methane is 90.0%, and the gas leaving the reactor contains 8 mol CO2/mol CO.
Carry out a degree-of-freedom analysis on the process. Then calculate the molar composition
of the product stream using molecular species balances, atomic species balances, and extents
of reaction.
