The Answer Should Be: Q = 124,395 Btu/lbm and S(N2) = 49.262 Btu/lbmR

After an industrial process, waste Ammonia gas, NH3, at 600R (Rankine) and 14.7 psia will be used in a furnace with air at 537R and 14.7 psia entering a separate inlet. After stoichiometric combustion, the products exit the fumace at 800R and 14.7 psia. For the NH3 gas, M=17tbmolelbm and its enthalpy of formation, hF=19,656Btu/lbmole. (a). Find the heat interaction from the fumace per lbmole of NH3. (b). Calculate the absolute entropy per lbmole of the N2 in the products at the exit
