For all cycles in this section, assume that you have exactly1.000 moles of gas and that the cycle is run reversibly. The knownstate parameters for the cycle will be given as the reducedtemperature Tr ≡ T /Tc and reduced pressurePr ≡ P/Pc, where Tc andPc are the critical temperature and pressure of assigneddiatomic molecule (N2). Assume the gas is a diatomic vander Waals gas.
1. You have a Carnot cycle that begins with an adiabaticexpansion from an initial state defined by a temperature ofTr = 1.75 and a pressure of Pr = 2.00 to apressure of Pr = 1.75. The system then undergoes anisothermal expansion to a pressure of Pr = 1.25,followed by an adiabatic compression and then an isothermalcompression back to the initial state. Calculate w, q, ∆U, ∆S,∆Ssur, ∆H, ∆A and ∆G for each step in the cycle and forthe total cycle.
(entropy S, enthalpy H, Gibbs energy G, and Helmholtz energyA.)
