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

Options

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`

Answer

B

Explanation

The extent of daviation showm by real gases from ideal behaviour in terms of compressibility factor (Z) which is defined as the ratio of pV and nRT.
Mathematically,`" " Z=(pV)/(nRT)`
Easily liquefiable gases such as `CO_2` exhibit larger devitation as compared to gases such as `H_2,O_2,N_2` etc., that liquefy with difficulty.
