Two (2) volatile liquids are mixed together in equal amounts. The resulting vapor pressure is 200 Torr. The vapor pressure of the pure liquids are P°A = 150 Torr and P°B = 220 Torr.
What can be concluded about the solution?
Nothing can be concluded
The A-B interaction is weaker than A-A plus B-B interaction
The two solutions are exhibiting ideal behavior
Vapor pressures are in general not additives
The A-B interaction is stronger than A-A plus B-B interaction
