MCQ
The value of Henry’s constant KH is ___________.
- AGreater for gases with higher solubility.
- BGreater for gases with lower solubility.
- CConstant for all gases.
- DNot related to the solubility of gases.
Explanation:
The value of Henry's constant KH is greater for gases with lower solubility because of the mathematical relation.
$\text{P}=\text{K}_\text{H}\times\text{x}$
$\text{K}_\text{H}=\frac{\text{P}}{\text{x}}$
where, KH represents Henry's constant, p is partial pressure of the gas in vapour phase, and x denotes mole fraction of the gas in solution. Thus KH is inversely proportional to mole fraction of gas in solution (representing its solubility).
