dG=SdT+VdP+allspeciesidni Here, the chemical potential is given per mole, rather than per molecule, so dNi is replaced by dni. Let's say the system contains M
dG=SdT+VdP+allspeciesidni Here, the chemical potential is given per mole, rather than per molecule, so dNi is replaced by dni. Let's say the system contains M different chemical species. A) How many Maxwell relations can be derived from this expression? B) Derive the relations for (Pi)T,nj and (Ti)P,nj. C) Now let's apply your findings to an aqueous solution that consists of two species: H2O (solvent) and solute. For a dilute solution, the volume of the solution can be approximated as V= nH2O/H2O+nsolute/solute, where the 's are the molar densities of pure water and solute. What does this information tell you about the dependence of H2O on pressure? dG=SdT+VdP+allspeciesidni Here, the chemical potential is given per mole, rather than per molecule, so dNi is replaced by dni.
