A system containing 2.50 mol of an ideal gas for which Cv,m=20.79 J mol-1k-1 is taken through the cycle in the diagram to the left in the direction indicated by the arrows. The curved path corresponds to PV=nRT, where T=T1=T3. a. Calculate q,w,delta U and Delta H for each segment and for the cycle. b. Calculate q,w,delta U and Delta H for each segment and for the cycle in which the direction of each process is reversed. In the graph all it says is the P initial =16.6 bar and Vinitial=1.00L and P final=16.6 bar and V final =25L
