According to Henry's Law, what is the effect of an increase in temperature on the Henry's law constant () and the resulting solubility of a gas in a liquid at constant pressure?

Question

According to Henry's Law, what is the effect of an increase in temperature on the Henry's law constant ($K_H$) and the resulting solubility of a gas in a liquid at constant pressure?

Prashant Kotian · Accepted Answer

Correct answer: B. The dissolution of a gas is exothermic. As temperature increases, equilibrium shifts backward, reducing solubility (). Since , to maintain constant while drops, must increase.
