With increase in reduced temperature, the fugacity co-efficient of a gas at constant reduced pressure___________________?
Correct answer: C. Increases
- A. Remain same
- B. Decreases
- C. Increases
- D. Decreases linearly
Explanation
At fixed reduced pressure, increasing reduced temperature generally weakens the relative effect of intermolecular attractions and moves the gas toward ideal behavior. The fugacity coefficient therefore generally increases toward unity.
