(b) Laboratory works were carried out to measure the composition of vapor and liquid of chloroform (1) and 1,4-dioxane (2) mixture. Vapor liquid equilibrium (VLE) data of the mixture at 323.15 K is shown in table below. Table 1. VLE data chloroform (1) and 1,4-dioxane (2) at 323.15 K P(kPa) X1 Y1 15.79 0.0000 0.0000 19.30 0.1757 0.3302 24.95 0.3615 0.6184 42.10 0.6718 0.9137 65.39 0.9398 0.9945 69.36 1.0000 1.0000 i. Examine the data available to generate the value of fugacity of species (1). f1 and provide a plot to identify the Henry's constant of component 1. (12 marks) By using the Henry's constant obtained in part (b) i, calculate the vapor phase composition of chloroform and 1,4-dioxane at x1=0.4 and pressure of 40 kPa. (4 marks)
