Lesser is the value of Z at a pressure, easy will be the liquefaction of the gas. Z < 1 shows the dominance of attractive forces. The order of liquefication as follows H2 < N2 < CH4 < CO2

Q. Compressibility factor $(Z = \frac{P V}{n RT})$ is plotted against pressure

What is the correct order of liquefiability of the gases shown in the above graph?

$H_{2} < N_{2} < C H_{4} < C O_{2}$

$C O_{2} < C H_{4} < N_{2} < H_{2}$

$H_{2} < C H_{4} < N_{2} < C O_{2}$

$C H_{4} < H_{2} < N_{2} < C O_{2}$

Lesser is the value of Z at a pressure, easy will be the liquefaction of the gas. Z < 1 shows the dominance of attractive forces.

The order of liquefication as follows

$H_{2} < N_{2} < C H_{4} < C O_{2}$
