Q1. Which of the following is NOT a colligative property?
- Osmotic pressure
- Elevation in boiling point
- Freezing point depression
- Vapor pressure of solvent
Q2. An azeotropic mixture of two liquids has a boiling point lower than either of the two pure liquids. This indicates:
- Positive deviation from Raoult's law
- Negative deviation from Raoult's law
- Ideal solution behavior
- No interaction between components
Q3. The unit of molality is:
- mol L⁻¹
- g L⁻¹
- mol kg⁻¹
- kg mol⁻¹
Q4. According to Henry's Law, the partial pressure of the gas in vapor phase (p) is proportional to the mole fraction of the gas (x) in the solution. The correct expression is:
- p = kH/x
- p = kH + x
- p = x/kH
- p = kH x
Q5. Which of the following conditions is favorable for dissolving a gas in a liquid?
- High pressure, high temperature
- Low pressure, low temperature
- High pressure, low temperature
- Low pressure, high temperature
