Q1: In a binary liquid solution of components A and B, if component A exhibits positive deviation from Raoult's law, then component B

ANS:A - exhibits positive deviation from Raoult's law.

In a binary liquid solution, if component A exhibits positive deviation from Raoult's law, it means that the vapor pressure of component A is higher than what would be expected based on Raoult's law. This typically occurs when there are stronger intermolecular forces between unlike molecules than between like molecules. Given that component A exhibits positive deviation, component B can exhibit either positive or negative deviation from Raoult's law:

• If component B also exhibits positive deviation, it means its vapor pressure is higher than expected, likely due to similar stronger intermolecular forces between unlike molecules.
• If component B exhibits negative deviation, it means its vapor pressure is lower than expected, likely due to weaker intermolecular forces between unlike molecules.
