Question: A solution is an equimolar mixture of two volatile components AA and BB. Pure AA has a vapor pressure of 60 torr and pure BB

A solution is an equimolar mixture of two volatile components AA and BB. Pure AA has a vapor pressure of 60 torr and pure BB has a vapor pressure of 120 torr. The vapor pressure of the mixture is 102 torr.

Part A

What can you conclude about the relative strengths of the intermolecular forces between particles of AA and BB (relative to those between particles of AA and those between particles of BB)?

What can you conclude about the relative strengths of the intermolecular forces between particles of and (relative to those between particles of and those between particles of )?

The intermolecular forces between particles AA and BB are weaker than those between particles of AA and those between particles of BB.
The intermolecular forces between particles AA and BB are stronger than those between particles of AA and those between particles of BB.
The intermolecular forces between particles AA and BB are the same as those between particles of AA and those between particles of BB.
Nothing can be concluded about the relative strengths of intermolecular forces from this observation.
