Gibbs duhem theorem
In thermodynamics, the Gibbs–Duhem equation describes the relationship between changes in chemical potential for components in a thermodynamic system: $${\displaystyle \sum _{i=1}^{I}N_{i}\mathrm {d} \mu _{i}=-S\mathrm {d} T+V\mathrm {d} p}$$where See more Deriving the Gibbs–Duhem equation from the fundamental thermodynamic equation is straightforward.
