💡 Solution & Explanation

The dissolution of a gas in a liquid is typically an exothermic process. As temperature increases, Le Chatelier's principle dictates that equilibrium shifts backward, reducing solubility ($\chi$). Since $P = K_H \chi$, for a constant pressure $P$, a lower $\chi$ requires a higher $K_H$. Therefore, $K_H$ increases with temperature.
