Question #1: (40 Marks) VLE data of methanol (1)/benzene (2) system at 760 mmHg are given below: TC x1 yl PY 11 70.67 62.87 58.64 58.10 59.90 0.026 0.088 0.333 0.699 0.898 0.267 0.457 0.559 0.633 0.760 1. Assuming an ideal vapor mixture, complete the table above; 2. Find the parameters of Van Laar model; 3. Draw the phase diagram T-x and T-y for Van Laar model. The plot should show the data and model predictions. Use Excel or Matlab; 4. Draw the equilibrium curve (showing experimental data and model predictions) Data: Antoine constants for methanol are A= 8.08097; B= 1582.27; C=239.7; valid over the temperature range 15 to 100C
