 The figure shows how increasing the pressure of a gas above a solution increases its solubility. Which law best describes this?
ABoyle's law
BRaoult's law
CHenry's law
DLe Chatelier's principle only
Answer & Solution
Correct answer: C. Henry's law
**Henry's law** quantitatively relates partial pressure of the gas to its mole fraction in solution (p = K_H x). Le Chatelier *qualitatively* predicts the shift toward more dissolution as pressure rises.
