Partial Molar Property - Differential Form of The Thermodynamic Potentials

Differential Form of The Thermodynamic Potentials

The thermodynamic potentials also satisfy

where is the chemical potential defined as (for constant nj with j≠i):

This last partial derivative is the same as, the partial molar Gibbs free energy. This means that the partial molar Gibbs free energy and the chemical potential, one of the most important properties in thermodynamics and chemistry, are the same quantity. Under isobaric (constant P) and isothermal (constant T ) conditions, knowledge of the chemical potentials, yields every property of the mixture as they completely determine the Gibbs free energy.

Famous quotes containing the words differential and/or form:

    “But how is one to make a scientist understand that there is something unalterably deranged about differential calculus, quantum theory, or the obscene and so inanely liturgical ordeals of the precession of the equinoxes.”
    —Antonin Artaud (1896–1948)

    “Now only a dent in the earth marks the site of these dwellings, with buried cellar stones, and strawberries, raspberries, thimble-berries, hazel-bushes, and sumachs growing in the sunny sward there.... These cellar dents, like deserted fox burrows, old holes, are all that is left where once were the stir and bustle of human life, and “fate, free will, foreknowledge absolute,” in some form and dialect or other were by turns discussed.”
    —Henry David Thoreau (1817–1862)
