Duhem-Margules equation

The Duhem – Margules equation is a thermodynamic statement about the relationship between two types of particles in a liquid , in which the vapor can be regarded as the ideal gas . It is named after Pierre Duhem and Max Margules .

${\displaystyle \left({\frac {d\ln \,P_{A}}{d\ln \,x_{A}}}\right)_{T,P}=\left({\frac {d\ln \,P_{B}}{d\ln \,x_{B}}}\right)_{T,P}}$,

Here P _A and P _{B are} the partial pressures of the steam of the two components and x _A and x _B are the molar proportions of the liquids.
