Question:
The following is a rule of thumb: For a binary system in VLE at low pressure, the equilibrium vapor-phase mole fraction y1 corresponding to an equimolar liquid mixture is approximately
where Psati is a pure-species vapor pressure. Clearly, this equation is valid if Raoult’s law applies. Prove that it is also valid for VLE described by Eq. (13.19), with ln γ 1 = A x22 and ln γ2 = A x21.
Eq. (13.19)
