Fugacity is most helpful in____________________?
Correct answer: A. Representing actual behaviour of real gases
- A. Representing actual behaviour of real gases
- B. Representing actual behaviour of ideal gases
- C. The study of chemical equilibria involving gases at atmospheric pressure
- D. None of these
Explanation
Fugacity is an effective pressure introduced to represent the escaping tendency of a real fluid, especially when it departs from ideal-gas behaviour. For an ideal gas, fugacity is simply equal to pressure, so it adds little value.
