Henry's Law states: $p = K_H \cdot x$ (partial pressure = $K_H$ × mole fraction of gas in solution).

$K_H$ is the Henry's Law constant. A higher $K_H$ means that for the same mole fraction, the gas exerts higher pressure — meaning the gas is less soluble, not more soluble.

Statement A is incorrect: higher $K_H$ means lower solubility (gas is harder to dissolve).

Statements B, C, D are all correct properties of Henry's Law.
