//(14.6)  Carbon monoxide at 25C, 1 atm enters a well-insulated reactor and reacts with the theoretical amount of air entering at the same temperature and pressure. An equilibrium mixture of CO2, CO, O2, and N2 exits the reactor at a pressure of 1 atm. For steady-state operation and negligible effects of kinetic and potential energy, determine the composition and temperature of the exiting mixture in K.


//solution

//The overall reaction is
//CO + .5O2 + 1.88N2  ------->   zCO + (z/2)O2 + (1-z)CO2 + 1.88N2
