In a closed combustion vessel, propane (C3H8) and air are mixed
at equivalence ratio of 1.11, temperature of 298 K, and pressure of
1 bar. The mixture is burned to produce solely CO2, CO, H2O, and
N2. The heat rejected from the vessel is 820 MJ/kmol of fuel. What
are the final temperature and final pressure of the mixture? Since
neither O2 nor H2 is present in the burned gas, dissociation can be
neglected.
