In a positive deviation the molecules find it easier to:
AAttract
BCombine
CDissolve
DEscape
Answer & Solution
Correct answer: D. Escape
1. The A-B attractions are weaker than those in the pure liquids.
2. A molecule is therefore held less tightly than when pure.
3. It escapes more easily, so the vapour pressure rises.
