Question
What factors are responsible for deviations for Raoult's law?
✓

Answer

If the force of attraction between A - B are different from A- A and B - B, there will be deviation from Raoult's law. As a result of this difference in interaction, there will be difference in vapour pressure of the mixture of A and B compared to pure A and pure B.
