Question:
Departures from Raoult’s law are primarily from liquid-phase nonidealities (γi ≠ 1). But vapor-phase nonidealities (ϕ i ≠ 1) also contribute. Consider the special case where the liquid phase is an ideal solution, and the vapor phase a nonideal gas mixture described by Eq. (3.36). Show that departures from Raoult’s law at constant temperature are likely to be negative. State clearly any assumptions and approximations.
Eq. (3.36)
