Assume there's 1 mol ideal mono-atomic gas in a 22.4L container at 300K. The initial entropy of the system is 100J/K. For the following processes, calculate: a) q and w for a reversible expansion to twice the volume, isothermally. b) S and G for irreversible isothermal expansion against a constant 0.5 bar external pressure, to a final internal pressure of 0.5 bar. c) U and H for adiabatic reversible expansion to twice the volume.
Mixed stream Ti = 300 K Q3.25 pts An ideal gas mixture consisting of 20% -300K O2 and 80% N2 (by mol) is separated into pure 02 P 1 atm and pure N2 streams. The gas mixture enters at 300 K, 1 atm, and pure gases leave at 300 K, 1 atm. Assuming steady-state, calculate the minimum work that is required to generate 1 kmol of pure 02. Assume that the heat transfer between the separator device and the surroundings...
