Gibbs free energy of gaseous phosphorus dimer

Chemical Engineering Science, 2018
Abstract We establish an analytical representation for the prediction of the molar Gibbs free energies of gaseous diatomic molecule substances. By comparing the predicted values to the experimental data for the gaseous phosphorus dimer, the availability of the Gibbs free energy calculation model is verified.

Generalized Gibbs free energy of confined nanoparticles

AIChE Journal, 2017
The nanoparticles generally show abnormal properties compared to those in the bulk phase, and they exhibit significant potential in various applications such as catalysis and energy conversion. However, the theoretical work for describing the properties of nanoparticles is limited with poor prediction capacity.

Excess gibbs free energy of mixing

Fluid Phase Equilibria, 1993
Abstract Narayanan, K.V. and Ananth, M.S., 1993. Excess Gibbs free energy of mixing. Fluid Phase Equilibria, 91: 77-86. The statistical mechanical approach to developing excess Gibbs free energy models for liquids using lattice theories in the Canonical ensemble is reexamined numerically in the light of the fundamental observations of Sandler et al.

Gibbs and Helmholtz Free Energies

2020
Two state functions have been formulated based on the spontaneity criterion for a given process, i.e. the positive entropy production: Gibbs free energy (for constant pressure and constant temperature conditions) and Helmholtz free energy (for constant volume and constant temperature conditions).

Gibbs free energy: The criteria for spontaneity

Journal of Chemical Education, 1992
This demonstration is useful in presenting a physical model for the four possible combinations of entropy and enthalpy to predict the spontaneity of a reaction.

Estimation of Gibbs Free Energy Functions

Journal of the American Ceramic Society, 1976
A computational method has been derived for the estimation of the molar heat capacity contribution to the Gibbs free energy function (fef T O ) above 298°K. This method, which is based on the observed temperature invariance of certain ratios of the integrals of these molar

Chemical Reactions and Gibbs Free Energy

2010
We have shown that when two things are mixed together we can calculate the entropy of mixing. We can also calculate the concentration of this mixture, as we did in the previous three examples. A most complete description of the chemicals and their mixtures is by using Gibbs free energy (we say it is free because it does not contain any pV work, like ...
