a. One mole of a monatomic ideal gas (CV,m = 3/2R and CP,m = 5/2R) is expanded isothermally and reversibly (P = Pext) from an initial volume of 1L (Vi = 1 L) at a temperature of 298 K (T = 298 K) to a final volume of 5 L (Vf = 5 L). Determine q, w, AU, AH, AS, ASsurr, and AStotal (or ASuniverse). b. Is the process described above spontaneous? Explain.
