Henry's law constants for aqueous soluti...

Henry's law constants for aqueous solution of `CO, O_(2), CO_(2)` and `C_(2)H_(2)` gases are respectively at `25^(@)C` as `58xx10^(3), 43xx10^(3), 1.61xx10^(3)` and `1.34xx10^(3)`. The solubility of these gases decreases in the order

A

`CO gt O_(2)gt CO_(2)gt C_(2)H_(2)`

B

`O_(2)gt CO_(2)gt CO gt C_(2)H_(2)`

C

`C_(2)H_(2)gt CO_(2)gt O_(2)gt CO`

D

`O_(2)gt CO_(2)gt C_(2)H_(2)gt CO`

Text Solution

Verified by Experts

The correct Answer is:
C
Greater the Henry's constant `(K_(H))`, lower is the solubility at the same pressure.
`therefore` Order of `K_(H) : CO gt O_(2)gt CO_(2)gt C_(2)H_(2)`
`therefore` Order of solubility : `C_(2)H_(2)gt CO_(2)gt O_(2)gt CO`
