Question
According to Henry's Law, what happens to the value of the Henry's law constant ($K_H$) and the resulting solubility of a gas when the temperature of the liquid is increased at a constant pressure?
Answer: A
💡 Solution & Explanation
Dissolution of gas is exothermic. Heating shifts the equilibrium backward, decreasing gas solubility ($\chi$). Since $P = K_H \times \chi$, to maintain constant $P$ while $\chi$ drops, $K_H$ must increase. Thus, $K_H \propto T$.
