4. The figure below shows a Px diagram for a binary system (component 1 and component 2) at 480 K. Black dots show data points from a series of constant mass expansion for four mixtures. Based on this diagram, answer the following: a) For a mixture of the two components to have a bubble point pressure of 6000 (kPa) at 480 K, what should be the overall composition of the mixture? b) Suppose you have 2.0 moles of component 1 and 2.0 moles of component 2 in the PVT cell at 6000 kPa and 480 K. The mixture shows two phases at equilibrium based on the diagram. What is the molar concentration of component 1 in the vapor phase? What is the molar concentration of component 1 in the liquid phase? c) What is the vapor mole fraction (Bv) for the two-phase systemin Part b? d) What is the K value for the component at 6000 kPa and 480 K? e) Is it possible for the binary mixture in part b to show a critical point at 480 K? Why or why not? 9000 8000 7000 Critical point
