Fugacity co-efficient of a substance is the ratio of its fugacity to__________________?
Correct answer: B. Pressure
- A. Mole fraction
- B. Pressure
- C. Activity
- D. Activity co-efficient
Explanation
The fugacity coefficient is defined as phi = f/P, so it compares a real substance's fugacity with its pressure. It approaches unity as the gas approaches ideal-gas behaviour.
