A 10-liter vessel at T = 300.0 K contains 0.340 kg of a vapor-liquid mixture of propane. i) Determine the pressure in the vessel and the fraction of the propane which is liquid. Use the Peng-Robinson equation, together with data from App. A, Koretsky, to describe the volumetric behavior of the fluid.
ii) If sufficient heat is added to just vaporize all of the liquid, determine the final temperature and pressure in the vessel.
