For the acetone (1)/methanol(2) system a vapor mixture for which z1 = 0,25 and z2 = 0.75 is cooled to temperature T in the two-phase region and flow* into a separation chamber at a pressure of 1 bar. If the composition of the liquid product is to be x1 = 0.175. what is the required value of T. and what is the value of y1? For liquid mixtures of this system to a good approximation:
In y1 = 0.64x22................................In y2 = 0.64x21
