1. You have the experimental data in the table below for a mixture of Methanol (1) and Benzene (2) in VLE at a temperature of 90 C. (a) Plot the pressure in bar as a function X over the entire range of x, from 0 to 1 and label the curve as bubble or dew point curve as appropriate. (b) Determine the parameters for the two-suffix Margules equations from the experimental values at x = 0.376. (c) Use the parameters to plot a fit of the pressure over the entire Xx range. Comment on the findings and methods to possibly improve the fit. X1 Y 0.117 0.502 0.257 0.594 0.376 0.618 0.549 0.65 0.707 0.689 0.856 0.765 mm Hg 1865 2113 2218 2273 2292 2208
