Question

Discuss chemical potential and its variation with temperature and pressure​

Answer 1

Answer:

The molar chemical potential is also known as partial molar free energy. When bothtemperature and pressure are held constant, chemical potential is the partial molar Gibbs free energy. ... In semiconductor physics, the chemical potential of a system of electrons at zero absolutetemperature is known as the Fermi energy.

Answer 2

Chemical potential and temperature and pressure variations.

Explanation:

• In thermodynamics, a species' chemical potential is the amount of energy that can be absorbed or released when the particle number of the species changes. The chemical potential of a species in a mixture is defined as the rate of change in a thermodynamic system's free energy as a function of the number of atoms or molecules of the species introduced to the system.

• As a result, it's the partial derivative of the free energy with respect to the amount of the species, with the concentrations of all other species in the mixture remaining constant. Partial molar free energy is another name for the molar chemical potential.

• Chemical potential is the partial molar Gibbs free energy when both temperature and pressure are kept constant. Because the free energy is at a minimum, the whole sum of chemical potentials and stoichiometric coefficients is zero at chemical equilibrium or phase equilibrium.
