The value of Henry's constant `K_(H)` is ……..

A

Greater for gases with higher solubility.

B

Greater for gases with lower solubility.

C

Constant for all gases.

D

Not related to the solubility of gases.

Text Solution

Verified by Experts

The correct Answer is:
B
Explanation : The value of Henry.s constant `K_(H)` is greater for gases with lower solubility because of the mathematical relation `- p=K_(H)X, K_(H)=p//X` where, `K_(H)` represents Henry.s constant, p is partial presure of the gas in vapour phase, and X denotes mole fraction of the gas in solution. Thus `K_(H)` is inversely proportional to mole fraction of gas in solution (representing its solubility).
