Chemical Engineering Thermodynamics (MCQs)

For an ideal gas, the activity co-efficient is

  • A. Directly proportional to pressure
  • B. Inversely proportional to pressure
  • C. Unity at all pressures
  • D. None of these
Answer: Option C.
Explanation: 

Activity coefficient measures the extent to which a real gas deviates from ideality.
Hence, for ideal gas activity coefficient = 1.
