Question

In a closed combustion vessel, propane (C3H8) and air with an equivalence ratio of 1.11 initially at 25\deg C burn to produce products consisting solely of carbon dioxide (CO2), carbon monoxide (CO), water (H2O) and atmospheric nitrogen. (i) If the heat rejected from the vessel is 770 MJ per kmol of fuel, show that the final temperature is about 1530 \deg C. (ii)If the initial pressure is 1 bar, estimate the final pressure. Lower calorific value of propane (- ∆H0)a, is 2 039 840 kJ/kmol of fuel at 25\deg C.
