Which one of the following gases has the lowest value of Henry law constant ?

A

`N_2`

B

`He`

C

`H_2`

D

`CO_2`

Text Solution

Verified by Experts

The correct Answer is:
D
According to Henry.s law the mass of a gas dissolved per unit volume of solvent is proportional to the pressure of the gas at constant temperature `m = K` p.i.e. as the solubility increasees, value of Henry.s law constant decreases. Since `CO_2` is most soluble in water among the given set of gases.
