Stability conditions of the one-phase multicomponent system

Let us consider an open thermodynamic system consisting of v components, i.e. containing particles of u kinds. I he first and second principles of thermodynamics written together for a quasi-static process in such a system represent the Gibbs fundamental equation in its energetic expression  [Pg.1]

V being the internal energj of the system, S the entropy, V the volume, T temperature, P pressure, p, and n, the chemical potential and number of moles of the tth component, respectively. [Pg.1]

This equation can be written in the entropy expression as well  [Pg.1]

As the internal energy U is a state function of the system. Equation 1 is a total differential  [Pg.1]

The variables in the right-hand side of Equation 1 under the sign of differentiation (i.e. S, V, 71,) are called thermodynamic coordinates. Let us denote them by a common letter Yi, I = 1,. .j/ - - 2 to write the following formulae compactly. By virtue of their additivity, the thermodynamic coordinates are extensive parameters.  [Pg.2]
