Use a - approach to model the vapor-liquid equilibrium of an ethyne [acetylene] (1) + 1, 1 difluoro ethane {R-152a] (2) system at 303.2 K. Treat the

liquid using the 2-parameter Margules equation and the vapor as an ideal solution (described by the virial equation). Report the following: 

∎ Raoult’s Law predictions 

∎ Modified Raoult’s Law predictions (ideal gas for the vapor phase) 

∎ Υ-Φ modeling results  

∎ Experimental data as symbols given in Table P12-30
