1. Gaseous propane (C3H8) at 77°F, 1 atm enters a reactor operating at steady state and burns with the theoretical amount of air entering separately at 240°F, 1 atm. An equilibrium mixture of CO2, CO, H2O(g) O2, and N2 exits at 3140°F, 1 atm. Determine the heat transfer between the reactor and its surroundings, in Btu per lbmol of propane entering. Neglect kinetic and potential energy effects.
2. One kmol of CO2 in a piston-cylinder assembly, initially at temperature T and 1 atm, is heated at constant pressure until a final state is attained consisting of an equilibrium mixture of CO2, CO, and O2 in which the amount of CO2 present is 0.422 kmol. Determine the heat transfer and the work, each in kJ, ifT is (a) 298 K, (b) 400 K.
