200 moles of ethane C2H6 are burned in a furnace with air that contains 945 moles of O2. The flue gas is measured and contains 20 moles of C2H6.

a. Is there excess oxygen? If so please determine how much excess.

b. The Orsat meter used to measure the components of the flue gas appears to be off. Can you confirm the composition of each species?

c. Calculate the heat transferred from the furnace provided that the ethane enters the system at 25 C, the air is preheated to 100 C and the flue gas exits at 400 C.
