In case of vapor-liquid equilibria, which of the following does not account for gas phase deviation from ideality ?
Correct answer: A. Activity co-efficient
- A. Activity co-efficient
- B. Fugacity co-efficient
- C. Use of equation of state
- D. None of these
Explanation
Gas-phase nonideality is represented using an equation of state or a fugacity coefficient. An activity coefficient corrects liquid-phase nonideality, so it does not account for gas-phase deviation.
