1. Calculate the equilibrium compositions of the liquid and vapour phases for an ideal solution of A and B at 60C and 50kPa. The vapour pressure of A and B at 60C are 62.52 and 17.65kPa, respectively. 2. A mixture contains A and B. The boiling point of A is 97C, and that of B is 115.5C. The vapour pressures of A and B are given in the table below. Assume that Raoult's and Dalton's laws apply. i. Calculate vapour-liquid equilibrium compositions at a constant pressure of 102.5kPa. ii. Obtain an empirical relation between the liquid and vapour phase compositions. iii. Construct T-x and T-y plots
