10 Questions
What is the main reason for the deviation from Raoult's law?
Nature of interactions at the molecular level
In a solution that shows positive deviation from Raoult's law, what is the relative strength of A-B interactions?
Weaker than A-A and B-B interactions
What is the result of weaker A-B interactions in a solution?
Increased vapour pressure
Which of the following solutions is expected to show positive deviation from Raoult's law?
Ethanol and acetone
What is the effect of adding acetone to pure ethanol?
Weakening of hydrogen bonds
Why does the solution of ethanol and acetone show positive deviation from Raoult's law?
Due to weakening of hydrogen bonds
What type of interactions are weaker in a solution that shows positive deviation from Raoult's law?
A-B interactions
What is the effect of weaker A-B interactions on the molecules of A (or B) in a solution?
They find it easier to escape
