Problem 2: Chloroform and Acetonitrile mixture Vapor-liquid equilibrium data for mixtures of chloroform and acetonitrile at 328.15K are given in the following table: Р X1 yi [kPa] [mol/mol] [mol/mol] 44.4 0.04 0.095 48.971 0.109 0.232 54.45 0.23 0.395 59.29 0.338 0.509 62.79 0.424 0.586 67.67 0.549 0.693 70.45 0.638 0.756 75.46 0.785 0.862 77.35 0.859 0.91 79.829 0.934 0.955 79.989 0.938 0.958 a) Use the given data to construct a P-xy diagram for this system. b) A pressure measuring device is used for a two-phase mixture at equilibrium reads 65 kPa at given system temperature. Use the P-xy diagram to estimate the mole fractions of chloroform in the liquid and vapor phases. c) An equimolar mixture is fed to an evacuated vessel and allowed to come to equilibrium at 328.15 K and 70 kPa. Estimate (1) the molar compositions of each phase and (2) The percentage of the total moles in the vessel that are in the vapor phase. d) Use Raoult's law to estimate the bubble-point pressure and vapor composition in equilibrium with an equimolar liquid mixture. e) Use Raoult's law to estimate the dew-point pressure and liquid composition in equilibrium with an equimolar mixture. f) How would the Pbubble and Pdew would change if composition of chloroform got increased to 0.8
