A fuel containing 50 mol% C2H6 and 50 mol% C3H8 enters a furnace at a rate of 200 mol/s, at 200 oC and Pgauge=5.0 atm. Air is fed to the furnace in a separate stream at 40% excess. All of the fuel is burned—the product contains no C2H6 and no C3H8. The ratio of CO2/CO in the product stream is 10/1 (in moles/moles).

Ideal gas constant, R= 0.08204 L atm/(mol K).

1. Calculate the partial pressure of C2H6 in the feed stream__________
