A compound has the follOwing physical properties:
Critical Temperature = 1000 K Critical Pressure = 20 atm Boiling temperature at atmospheric pressure = 300 K Molar Volume of saturated liquid at atmospheric pressure = 0.1 L/mol Coefficient of Thermal Expansion for LIQUID is constant at 0.001 K-1 Isothermal Compressibility of LIQUID is constant at 5x10-4atm-1 Ideal Gas Heat Capacity is Cp*= 4R Heat capacity in the liquid phase is constant at Cv=0.3 L atm/mol K, In the gas/vapor phase, can be described by the equation of state: PV = RT + (BP3) Where B = 0.05 L mol-1atm-2 A) A stream of vapor enters a turbine at T=800 K and P=10 atm, and it leaves at T=500 K and P=2 atm. Find ?H and ?S for the vapor in this process. B) Derive general equations (i.e., valid for any fluid, not just this compound) that express ((??H)/(??V))_Tand ((??H)/?T)_?Ventirely in terms of measureable properties. Your expressions can include P, V, T, CP, CV, and/or their derivatives, as well as the gas constant R. C) The compound described above, initially in the liquid phase at T=300 K and P=1 atm, is placed in a rigid container and cooled to T=275 K. What is the change in molar enthalpy of the compound for this process?
