Ammonia gas enters a reactor with 30% more dry air (no water vapor) than is required for complete conversion (4NH3 + 5O2 --> 4NO + 6H2O). These gases enter the reactor at 75c and exit at 600c. How much heat is required per mole of ammonia fed?

Benzaldehyde is produced from toluene in the catalytic reaction C6H5CH3 + O2 ? C6H5CHO + H2O Dry air and toluene vapor are mixed and fed to the reactor at 350.0°F and 1 atm. Air is supplied in 100.0% excess. Of the toluene fed to the reactor, 13.0% reacts to form benzaldehyde and 0.100% reacts with oxygen to form CO2 and H2O. The product gases leave the reactor at 379°F and 1 atm. Water is circulated through a jacket surrounding the...

Methane gas is burned completely with 30% excess air in a furnace operating at one atmosphere. Both the methane and air enter the furnace at 40ºC saturated with water vapor. The flue gas (furnace exhaust) leaves the furnace at 1000ºC. The flue gas then passes through a heat exchanger and emerges at 60ºC. If 260 mole/sec of methane fed to the furnace, how much heat is lost from the furnace, and how much heat is transferred in the heat exchanger?...
