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

Answer»

Greater for gases with higher SOLUBILITY.
Greater for gases with lower solubility.
CONSTANT for all gases.
Not related to the solubility of gases.

Solution :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).
