Solution of methanol and ethanol are substantially ideal.

Question

(a) Compute the vapour-liquid equilibria for this system at 1 and at 5 atm abs pressure, and plot xy and txy diagrams at each pressure
(b) For each pressure compute relative volatilities , and determine an average value.
( c ) Using Eq.with the average volatilities ,compare the values of y* at each value of x so obtained with those computed directly from the vapour pressures.
