The activity co-efficient of a solution, which accounts for the departure of liquid phase from ideal solution behaviour________________?
Correct answer: C. Is a function of the liquid phase composition
- A. Measures the elevation in boiling point
- B. Is not dependent on the temperature
- C. Is a function of the liquid phase composition
- D. Measures the depression in freezing point
Explanation
The activity coefficient measures how a liquid component departs from ideal-solution behaviour and generally varies with liquid composition, temperature, and pressure. Among the choices, its dependence on liquid composition is the valid statement.
