5) Carbon dioxide (CO2) and oxygen (O2) in a 1:2 molar ratio enter a reactor operating at steady state in separate streams at 1 atm, 127°C and 1 atm, 277°C, respectively. An equilibrium mixture of CO2, CO, and O2 exits at 1 atm. If the mole fraction of CO in the exiting mixture is 0.1, determine the rate of heat transfer from the reactor, in kJ per kmol of CO2 entering. Ignore kinetic and potential energy effects. (Ans: 425239 kJ/kmol)
