Free energy, fugacity and activity co-efficient are all affected by change in the temperature. The fugacity co-efficient of a gas at constant pressure ______________ with the increase of reduced temperature?
Correct answer: D. Increases
- A. Decreases
- B. Decreases logarithmically
- C. Remains constant
- D. Increases
Explanation
At constant pressure, increasing reduced temperature generally makes a gas behave more ideally, so its fugacity coefficient moves toward unity and increases. This is the usual corresponding-states trend intended here.
