The Lewis-Randall rule states that the coefficient of this property in an ideal solution is equal to its coefficient for a pure species in the same physical state, temperature, and pressure of the solution. It was devised to quantify differences between the properties of pure and salt water.  It is equal to the exponential of the standard reference free energy divided by the kinetic temperature.  For an ideal gas, its coefficient is by definition unity. FTP, what thermod
