Question:
Which one of the following pairs will show positive deviation from Raoult's Law?
Which one of the following pairs will show positive deviation from Raoult's Law?
Show Hint
Positive deviation occurs when solute-solvent interactions are weaker than self-interactions, increasing vapor pressure.
Updated On: Dec 26, 2024
- Water - HCl
- Benzene - Methanol
- Water - $HNO_3$
- Acetone - Chloroform
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Benzene and methanol show positive deviation from Raoult's law because their solute-solvent interactions are weaker than their individual self-interactions, resulting in a higher vapour pressure than expected.
