Chemical potential of pure substance
Chemical potential was first described by the American engineer, chemist and mathematical physicist Josiah Willard Gibbs. He defined it as follows: If to any homogeneous mass in a state of hydrostatic stress we suppose an infinitesimal quantity of any substance to be added, the mass remaining homogeneous and its entropy and volume remaining unchanged, the increase of the energy of the mass divided by the quantity of the sub… WebThe chemical potential is directly equal to the Fermi energy in some ideal ( T = 0) systems. This chemical potential is dependent on electron mass, number of electrons and …
