Question
The value of Henry’s constant $K_H$ is $........$
✓
Answer
The value of Henry's constant $K_H$ 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, $K_H$ 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 $K_H$ is inversely proportional to mole fraction of gas in solution $($representing its solubility$).$
