1.The Wilson parameters for the system acetone (1)- methanol (2) are obtained form the following values V_1= 74.0510^(-6) m3/mol and V_2= 40.7310^(-6) m3/mol. The vapour pressures are given by lnP_1^S=14.39155-2795.817/(T-43.198) lnP_2^S=16.59381-36s44.297/(T-33.435) where P is in kPa and T in in K. Draw the P-x-y diagram at 333 K. (Use 5 sets of data)
