. A sample consisting of 150 g of CO molecules at 300 K is expanded isothermally from an initial pressure of 5.0 bar to a final pressure of 2.0 bar. Calculate q, w, ∆U, ∆H, ∆Ssys, ∆Ssurr, and ∆Stotal for the process two ways: (a) reversibly and (b) irreversibly against a constant pressure of 2.0 bar. Cp,m is constant at a value of 29.14 J/mol* K, and temperature of the surroundings is 273 K. State whether each process is spontaneous.
