K(H) value for' Ar(g),CO(2g),HCHO(g) and...

`K_(H)` value for' `Ar_(g),CO_(2g),HCHO_(g)` and `CH_(4g)` are 40.39, 1.67, `1.83xx10^(-5)` and 0.413 respectively.
Arrange these gases in the order of their in creasing 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`

Text Solution

Verified by Experts

The correct Answer is:
C
Value of `K_(H)` depends upon nature of gases dissolved in water

Hence correct order is `Ar lt CO_(2)ltCH_(4)ltHCHO`.
