Critical compressibility factor for all substances___________________?
Correct answer: A. Are more or less constant (vary from 0.2 to 0.3)
- A. Are more or less constant (vary from 0.2 to 0.3)
- B. Vary as square of the absolute temperature
- C. Vary as square of the absolute pressure
- D. None of these
Explanation
The critical compressibility factor, Zc = PcVc/(RTc), is approximately similar for many substances and commonly lies around 0.2 to 0.3. It is not generally proportional to the square of temperature or pressure.
