Solution to PS 7 Problem 1 ü (a), (b) See the plots below. The actual data deviates positively from the Rault' s law. This indicates that the interaction between CS2/benzene is unfavorable compared to CS2/CS2 or benzene/benzene. p A = 360.924 Torr; p B = 95.137 Torr; p A @ xA _ D = p A × xA; p B @ xA _ D = p B × H 1 xA L ; p total @ xA _ D = p A @ xA D + p B @ xA D ; y A @ xA _ D = Simplify @ p A @ xA p total @ xA DD ; P0 = Plot @ 0, 8 xA, 0, 1 < , PlotRange 8 0, 400 < , AxesLabel 8 "y A ", "p A " <D ; P1 = Plot @ p total @ xA Torr, 8 xA, 0, 1 < , PlotRange 8 0, 400 < , AxesLabel 8 "x A ", "p A " <D ; P2 = ParametricPlot @8 y A @ xA D ,p total @ xA Torr < , 8 xA,0,1 < , AxesLabel 8 "y A ", "p total " <D ; P3 = Plot @ p A @ xA Torr, 8 xA, 0, 1 < , PlotRange 8 0, 400 < , AxesLabel 8 "x A ", "p A " <D ; P4 = ParametricPlot @8 y A @ xA D ,p A @ xA Torr < , 8 xA,0,1 < , AxesLabel 8 "y A ", "p A " <D ; P5 = Plot @ p B @ xA Torr, 8 xA,0,1 < , PlotRange 8 0, 400 < , AxesLabel 8 "x A ", "p B " <D ; P6 = ParametricPlot @8 y A @ xA D ,p B @ xA Torr < , 8 xA,0,1 < , AxesLabel 8 "y A ", "p B " <D ; P7 = ListPlot @ xpdata, PlotRange 8 0, 400 <D ; P8 = ListPlot @ ypdata, PlotRange 8 0, 400 <D ; Show @ P3, P1, P5, P7 D Show @ P0, P2, P4, P6, P8 D 0.0 0.2 0.4 0.6 0.8 1.0 x A 100 200 300 400 p A
