A consideration of the correct calculation of thermodynamic parameters of adsorption [PDF]

Journal of the Serbian Chemical Society, 2007
The Langmuir and Freundlich isotherm equations have been widely used for interpreting various adsorption processes. There are, however, many serious mistakes in the literature in determination or calculation of thermodynamic parameters, especially in the

Calculation of thermodynamic parameters of metals

Литьë и металлургия, 2021
Method of calculation of thermodynamic parameters of metals has been developed. Based on the thermodynamic parameters of the metals, it is shown that the Gibbs molar volumetric energy has a negative value.

eQuilibrator--the biochemical thermodynamics calculator [PDF]

Nucleic Acids Research, 2011
The laws of thermodynamics constrain the action of biochemical systems. However, thermodynamic data on biochemical compounds can be difficult to find and is cumbersome to perform calculations with manually. Even simple thermodynamic questions like 'how much Gibbs energy is released by ATP hydrolysis at pH 5?' are complicated excessively by the search ...

Thermodynamic modeling of the Sc-Zn system coupled with first-principles calculation [PDF]

Journal of Mining and Metallurgy. Section B: Metallurgy, 2012
The Sc-Zn system has been critically reviewed and assessed by means of CALPHAD (CALculation of PHAse Diagram) approach. By means of first-principles calculation, the enthalpies of formation at 0 K for the ScZn, ScZn2, Sc17Zn58, Sc3Zn17 and ScZn12 have

Thermodynamic assessment of the Co-Mg binary system [PDF]

Journal of Mining and Metallurgy. Section B: Metallurgy, 2022
No thermodynamic description was performed for the Co-Mg binary system according to literature review. Consequently, this binary system has been investigated by means of CALPHAD (CALculation of PHAse Diagrams) approach in the present work.

Influence of the model used for the calculation of equilibrium constants at moderate temperature for electrolytes [PDF]

MATEC Web of Conferences, 2023
The formation of a solid mineral deposit can cause major problems in the conduct of industrial processes such as high pressure acid leaching. Knowledge of the chemical speciation and solubility product of the mineral can help control or inhibit its ...

Calculations of Thermodynamic Sulfur Isotope Effect [PDF]

Journal of Nuclear Science and Technology, 1985
The isotopic reduced partition function ratios (RPFR), (s/s')f, for the 34S/32S isotopic pair were calculated for 24 sulfur compounds between 10 and 2,000K. Their magnitudes were in the following sequences; at low enough temperatures at which In(s/s')f depends only on the isotopic difference in frequency-sum, SF6>SO2F2>SF5Cl>SF5Br>SO4 2->SO2Cl2>SO3 ...

Quasi-particles, thermodynamic consistency and the gap equation [PDF]

, 2017
The thermodynamic properties of superconducting electrons are usually studied by means of the quasi-particles distribution; but in this approach, the ground state energy and the dependence of the chemical potential on the electron density cannot be ...
