One of the important approach to the study of real gases involves the analysis of parameter `Z` called the compressibility factor `Z = (PV_(m))/(RT)` where `P` is pressure, `V_(m)` is molar volume, `T` is absolute temperature and `R` is the universal gas constant. such a relation can also be expressed as `Z = ((V_(m)real)/(V_(m)ideal))` (where `V_(m ideal)` and `V_(m real)` are the molar volume for ideal and real gas respectively). Gas corresponding `Z lt 1` have attractive forces amoung constituent particles. As the pressure is lowered or temperature is increased the value of `Z` approaches 1. (reaching the ideal behaviour)
For a real gas `G Z gt 1` at `STP` Then for 'G': Which of the following is true:

Options

A. 1 mole of the gas occupies 22.4 L at `NTP`
B. 1 mole of the gas occupies 22.4 L at pressure higher than that at `STP` (keeping temperature constant)
C. 1 mole of the gas occupies 22.4 L at pressure lower than that at `STP` (keeping temperature constant)
D. None of the above

Answer

B
