part b, please!

3.1 Two moles of nitrogen are initially at 10 bar and 600 K (state 1) in a horizontal pistom/cylin der device. They are expanded adiabatically to 1 bar (state 2). They are the heated at con stant volume to 600 K (state 3). Finally, they are isothermally returned to state 1. Assume that N, is an ideal gas with a constant heat capacity as given on the back flap of the book, Neglect the heat capacity of the piston/cylinder device. Suppose that heat can be supplied or rejected as illustrated below. Assume each step of the process is reversible. Hot Reservoir Removable Insulation WS Cold Reservoir (a) Calculate the heat transfer and work done on the gas for each step and overall. (b) Taking state 1 as the reference state, and setting U = 0, calculate U and H for the nitrogen at each state, and AU and A4 for each step and the overall and Wec
