From Table-10 we found the change of excess Gibbs energy (IG*E) for the ternary liquid system are positive in all the temperatures and increase with mole fraction of 2,5 hexandione .
Diederichs demonstrates that when such a steady state cycling between ATP formation and splitting is reached, all involved potential thermodynamic functions of the state, for example, Gibbs energy, enthalpy, and entropy remain unchanged, which means that no heat can be produced and/or exchanged for ATP cycling under the given conditions.
For the analysis of a multicomponent system, a thermodynamic model was used in which the free Gibbs energy for a four-component solution was considered as a mixture of four hypothetical binary compounds in the form [6]:
The parameter is formally defined as Gibbs energy of electrochemical process by the classical equation
Keywords: dynamic programming, Bayesian framework, Markov random fields (MRFs), edges-preserving smoothing, Gibbs energy, pair-wise potential functions
The molecular Gibbs energy of the association-dissociation process can be computed as
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].
The Gibbs energy functions of the pure elements (Mg, Na) are taken from the SGTE (Scientific Group Thermo data Europe) compilation of Dinsdale [89].
