For a binary system consists of the cyclopentane (species 1) and cyclohexane (species 2), this binary 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 = x,Pjat Antoine equation: In Piat (kPa) = A, - T("C)+C Parameters for Antoine Eqn.
