Problem: A solution is an equimolar mixture of two volatile components A and B. Pure A has a vapor pressure of 50 torr and pure B has a vapor pressure of 100 torr. The vapor pressure of the mixture is 85 torr.What can you conclude about the relative strengths of the intermolecular forces between particles of A and B (relative to those between particles of A and those between particles of B)?

Assuming that the solution of gases is ideal, the vapor pressure of the mixture should be:

Vapor Pressuremix=50 torr+85 torr2Vapor Pressuremix=67.5 torr
