`K_(H)` value for Ar(g),CO(g), HCHO(g) and `CH_(4)(g)` are 40.39 , 1.67 ,`1.83xx10^(-5)` and 0.413 respectively. Arrange these gases in the order of their increastively solubility.
A. HCHO lt `CH_4` lt `CO_2` lt Ar
B. HCHO lt `CO_2 lt CH_4 lt Ar`
C. `Ar lt CO_2 lt CH_4 lt HCHO`
D. `Ar lt CH_4 lt CO_2 lt HCHO`

Correct Answer - C
Higher the value of `K_H`, the lower is the solubility of gas in the liquid . Thus, the order of increasing solubility is `{:(,Ar,lt,CO_2,lt,CH_4,lt,HCHO),(K_H "value",40.39,,1.67,,0.413,,1.83xx10^(-5)):}`
