Propane (C3H8) at standard temperature and pressure (298K and 1 atm) is combined with air at 500K and 1 atm in stoichiometric proportions and burned in a control volume (open system). a. (10 points) How many moles of air do we need to burn 1 mole of fuel at stoichiometric conditions? (You can assume the products are only CO2, H0 and N2.) b. (25 points) Assuming complete ideal combustion, what is the heat transfer in kJ/kmol fuel if the final temperature is 1000K? Enthalpy values (in kJ/kmol) for the various reactants and products are given in the table below. hf(T=298K) [h (T-500K)- h (298K)] [h (T-1000K)- h (298K)] C3H8 -103,847 0 0 N CO 0 -393,546 6,097 5,920 8,301 22,721 21,468 33,425 HOgas -241,845 6,947 24,993 Propane (C3H8) at standard temperature and pressure (298K and 1 atm) is combined with air at 500K and 1 atm in stoichiometric proportions and burned in a control volume (open system). a.
