    \[{{K}_{H}}\](kbar) values for \[A{{r}_{(g)}}\], \[C{{O}_{2(g)}}\], \[HCH{{O}_{(g)}}\]and \[C{{H}_{4(g)}}\] are 40.39, 1.67, \[1.83\times {{10}^{-5}}\]and 0.413 respectively. Arrange these gases in the order of their increasing solubility.

    A) \[HCHO<C{{H}_{4}}<C{{O}_{2}}<Ar\]

    B) \[HCHO<C{{O}_{2}}<C{{H}_{4}}<Ar\]

    C) \[Ar<C{{O}_{2}}<C{{H}_{4}}<HCHO\]

    D) \[Ar<C{{H}_{4}}<C{{O}_{2}}<HCHO\]

    Correct Answer: C

    Solution :

    Higher the value of \[{{K}_{H}}\] at a given pressure, the lower is the solubility of the gas.
