For an ideal gas, the activity co-efficient is_________________?
Correct answer: C. Unity at all pressures
- A. Directly proportional to pressure
- B. Inversely proportional to pressure
- C. Unity at all pressures
- D. None of these
Explanation
An ideal gas has no intermolecular interactions and obeys the ideal-gas reference behaviour, so its activity coefficient is unity. A pressure-dependent activity coefficient would indicate non-ideal behaviour.
