For a binary system consist of ortho-xylene (o-xylene) [species 1] and para-xylene (p-xylene) [species 2], this system is found to obey Raoult's law. It is known that Antoine equation allows the quick computation of vapor pressures of pure species. Raoult's law: yP = xpsat Antoine equation: Parameters for Antoine Eqn. Temp.
