Worksheet: Chemical Potentials in Mixtures

In this worksheet, we will practice using the Gibbs–Duhem equation to calculate the chemical potentials of species in an equilibrium mixture.


The equilibrium vapor pressure of water at 298 K is 32×10 bar. Is the chemical potential of HO()2l at 298 K and 2.7×10 bar less than, equal to, or greater than the chemical potential of HO()2g at the same temperature and pressure?

  • AGreater than
  • BThere is not enough information provided to answer this question.
  • CEqual to
  • DLess than
