Characterizing the equilibrium state of non-stoichiometric metal oxides in relation to oxygen pressure, Stoklosa defines the total standard Gibbs energy of the formation of defects at a given deviation from the stoichiometry, and develops a method for determining complete diagrams of concentrations of the point defects which takes into account the minority defects.
A thermodynamic model based on the Gibbs energy difference was used to describe the degree of gelatinization as a function of both pressure and temperature.
Since the calculation of the Gibbs energy was carried out at temperatures above the phase transition temperatures of the reactants, the enthalpies and entropies of reactions were calculated separately for each interval between the temperatures of phase transformations, including intervals of 25[degrees]C (298K) to the temperature of the first phase transformation from the last phase transformation to the final temperature [14].
Several thermodynamic works have been published based on the enthalpic and entropic contributions to the Gibbs energy of solution of sulfonamides (Delgado, D.
Abstract: Excess molar volume V E , energy of activation 6E , Gibbs energy change 6G and entropy change6S have been investigated for this study density and viscosity measurements of Acetonitrile (AN), 3-hydroxypropionitrile(3-HPN) and 50% mixture of AN + 3-HPN and alkali metal bromides (Li,Na,K,Rb and Cs)Br in AN, 3-HPN and50%AN+3-HPN over the concentration range (0.
The negative values for Gibbs energy indicate that the adsorption is spontaneous, Table 2.
Several methods exist to calculate the Gibbs energy and the one presented in [SantaLucia et al.

Then, this study calculated the real Gibbs energy of each oxidation reaction.
The graduate textbook covers the Gibbs-Duhem equation, temperature-composition diagrams, configurational entropies, Helmholtz energy minimization, total Gibbs energy, Ellingham diagrams, and analytical representation of thermodynamic properties.
