Input (English): The Duhem-Margules equation can be used to derive it and a similar relation, and this law can be related to the Lewis-Randall rule by the Gibbs-Duhem equation. Its proportionality constant gives a relation between the chemical potential of solute atoms and infinite dilution; that constant is determined experimentally by measurements on a liquid-vapor equilibrium and the value depends on temperature as well as the solute-solvent pair involved. It explains decompression sickness in divers and the fizzing of soda when a bottle is opened. For 10 points, name this law of chemistry that relates the dissolved concentration of a gas to its partial pressure above the solvent.
Output (English): Science
