The variation of compressibility factor (Z) with pressure (p in bar) for some gases are shown in the figure below. Identify the gases (A),(B) and (C) respectively (A) real gas, N 2, CO 2 (B) ideal gas, H 2, CO 2 (C) ideal gas, CO 2, H 2 (D) real gas , H 2, CO 2

The extent of deviation shown by real gases from ideal behaviour is measured in terms of compressibility factor

(Z)

which is defined as the ratio of

p V

and

n RT

.

Mathematically,

Z = \frac{p V}{n RT}

For ideal gases,

Z = 1

Easily liquefiable gases such as

C O_{2}

exhibit larger deviation as compared to gases such as

H_{2}, O_{2}, N_{2}

etc., that liquefy with difficulty.
