The Boyle temperature of three gases are given in the table :
`{:("Gas","Boyle Temperature (K)",),("Ethene",735,),("Oxygen",400,),("Hydrigen",110,):}`
If the compressibility factor was measured at 400 K, the gases are :

Options

A. I-ethene, II-oxygen, III-hydrogen
B. I-hydrogen, II-ethene, III-oxygen
C. I-hydrogen, II-oxygen, III-ethene
D. I-oxygen, II-ethene, III-hydrogen

Answer

C

Explanation

At Boyle temperature of oxygen, its compressibility factor will be unity, i.e., II is oxygen gas. More the compressibility factor, greater is the negative deviation from ideal behaviour
`:. I rarr " Hydrogen ", III rarr " ethene"`
