2. (Adapted from problem 11.14 in Elliott and Lira) A vapour/liquid experiment for the carbon disulphide(1) + chloroform(2) system has provide the following data at 298K:P1sat=46.85kPa, P2sat=27.3kPa,x1=0.2,y1=0.363,P=34.98kPa. Estimate the bubble pressure at 298K and x1=0.6, using the modified Raoult's law with a) The one-parameter Margules equation. b) The two-parameter Margules equation
