Definition

partial derivative of the Gibbs energy (ISO 80000-5: Thermodynamics) with respect to amount $n_{X}$ of substance $X$ (amount of substance) at constant temperature $T$ (ISO 80000-5: Thermodynamics) and pressure $p$ (ISO 80000-4: Mechanics):

μ_{X} = {(\partial G / \partial n_{X})}_{T, p}

dérivée partielle de l'enthalpie libre (ISO 80000-5: Thermodynamics) par rapport à la quantité de matière $n_{X}$ (amount of substance) du constituant $X$ (amount of substance) à température $T$ (ISO 80000-5: Thermodynamics) et pression $p$ (ISO 80000-4: Mechanics) constantes:

μ_{X} = {(\partial G / \partial n_{X})}_{T, p}

Notes

For a pure substance, where $G_{m}$ is the molar Gibbs energy. In a mixture, $μ_{B}$ is the partial molar Gibbs energy.

In condensed matter physics, the chemical potential of electrons is energy.

Pour un corps pur, où $G_{m}$ est l'enthalpie libre molaire. Dans un mélange, $μ_{B}$ est l'enthalpie libre molaire partielle.

En physique de la matière condensée, le potentiel chimique des électrons est l'énergie.
