Chemistry

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 yourassigned diatomic molecule, N2. Assume the gas is adiatomic van der Waals gas.

You have an Ericsson cycle that begins with an isothermalexpansion from an initial state of Tr = 1.75 andPr = 2.00 to a pressure of Pr = 1.75. Thesystem then undergoes isobaric expansion to a temperature ofTr = 2.00, followed by isothermal compression and thenisobaric compression back to the initial state. Calculate w, q, ∆U,∆S, ∆Ssur, ∆H, ∆A and ∆G for each step in the cycle and for thetotal cycle.

(entropy S, enthalpy H, Gibbs energy G, and Helmholtz energyA)
