Levine, Physical Chemistry, Sections 4.6{4.8, 6.1{6.2 Key Concepts For a single component system consisting of an ideal gas, we were able to arrive at an expression for the chemical potential by integrating our expression for dG for a single component system at constant temperature (dG = VdP) between some reference pressure P and the pressure of interest P: (T;P) = (T) +RT ln PP where (T) is the chemical potential of the pure gas in the reference state (usually P = 1 bar) We can now arrive at expressions for related quantities such asS, since we know that S = @G @T P;n = @ @T P;n (where the bar above the quantity means per mole, or the molar entropy). For an ideal gas in a mixture, we have to account for the actual amou...
