van der Waals Cycles For all cycles in this section, assume that you have exactly 1.000 moles of gas and that the cycle is run reversibly. The known state parameters for the cycle will be given as the reduced temperature Tr T=Tc and reduced pressure Pr P=Pc, where Tc and Pc are the critical temperature and pressure of your assigned diatomic molecule. Assume the gas is a diatomic van der Waals gas. 1. You have a Carnot cycle that begins with an adiabatic expansion from an initial state dened by a temperature of Tr = 1:75 and a pressure of Pr = 2:00 to a pressure of Pr = 1:75. The system then undergoes an isothermal expansion to a pressure of Pr = 1:25, followed by an adiabatic compression and then an isothermal compression back to the initial state. Calculate w, q, ΔU, ΔS, ΔSsur, ΔH, ΔA and ΔG for each step in the cycle and for the total cycle.
