Activity co-efficient is a measure of the____________________?
Correct answer: C. Departure from ideal solution behaviour
- A. Vapour pressure of liquid
- B. Departure of gas phase from ideal gas law
- C. Departure from ideal solution behaviour
- D. None of these
Explanation
The activity coefficient compares a component's actual activity with its ideal-solution value, so it measures departure from ideal solution behaviour. Departure of a gas from ideality is instead described by the fugacity coefficient.
