TL;DR: In this article, a mass action law is used to determine the composition of a pure nitrogen mixture out of thermal equilibrium, and the composition evolution versus time is determined from a kinetic method modified to take into account different temperature hypotheses and thermal disequilibria.
Abstract: The disequilibrium between the temperatures (excitation, rotation, vibration, translation) in plasmas lead us to specific chemical potentials. Then, they are used to develop a mass action law in a multitemperature plasma. This mass action law enables us to determine the composition of a pure nitrogen mixture out of thermal equilibrium.
The composition evolution versus time is determined from a kinetic method modified to take into account different temperature hypotheses.
The composition and different thermodynamic properties of a pure nitrogen mixture are given at the chemical equilibrium, then versus time for various temperature hypotheses and thermal disequilibriums.

TL;DR: In this paper, a mean spherical approximation based mass action law approach was developed to describe the influence of ion association on solvent and solution dielectric constants in electrolyte solutions. But the results were compared with recent experimental data for aqueous solutions of nitrate and formate salts and a fair agreement was obtained.
Abstract: Mean spherical approximation - mass action law approach is developed to describe the influence of ion association on solvent and solution dielectric constants in electrolyte solutions. The dependences of the dielectric constants on electrolyte concentration, ionic sizes, and the degree of ion association are analyzed. The results are compared with recent experimental data for aqueous solutions of nitrate and formate salts and a fair agreement is obtained.

TL;DR: In this article, the authors consider a system of reaction-diffusion equations describing the reversible reaction of two species forming a third species according to mass action law kinetics with arbitrary stochiometric coefficients (equal or larger than one).
Abstract: We consider a system of reaction-diffusion equations describing the reversible reaction of two species $\mathcal{U}, \mathcal{V}$ forming a third species $\mathcal{W}$ and vice versa according to mass action law kinetics with arbitrary stochiometric coefficients (equal or larger than one).
Firstly, we prove existence of global classical solutions via improved duality estimates under the assumption that one of the diffusion coefficients of $\mathcal{U}$ or $\mathcal{V}$ is sufficiently close to the diffusion coefficient of $\mathcal{W}$.
Secondly, we derive an entropy entropy-dissipation estimate, that is a functional inequality, which applied to global solutions of these reaction-diffusion system proves exponential convergence to equilibrium with explicit rates and constants.

TL;DR: Based on the phase diagrams, measured activities and in the light of mass action law as well as the coexistence theory of metallic melts involving compound formation, the calculated results agree well with experimental values, showing that the models formulated can embody the structural characteristics of the corresponding melts and that when activities of a binary system involving peritectic exhibit negative deviation relative to Raoult's law, a single phase calculating model will give best agreement with experiments as discussed by the authors.
Abstract: Based on the phase diagrams, measured activities and in the light of mass action law as well as the coexistence theory of metallic melts involving compound formation, calculating models of mass action concentrations for metallic melts AgIn, AgSn InSn and AgInSn have been formulated The calculated results agree well with experimental values, showing that the models formulated can embody the structural characteristics of the corresponding melts It is clear from the calculation, that when activities of a binary system involving peritectic exhibit negative deviation relative to Raoult's law, a single phase calculating model will give best agreement with experiments; and correspondingly, for ternary metallic melts formed from three binary systems involving peritectic, a single phase calculating model should also be used to evaluate their mass action concentrations

TL;DR: In this paper, the magnetic field dependence of the Hall coefficient in p-type samples of CdxHg1-xTe, with x in the region of 025, was determined down to lower temperatures than has previously been possible.
Abstract: From studies of the magnetic-field dependence of the Hall coefficient in p-type samples of CdxHg1-xTe, with x in the region of 025, the intrinsic concentration has been determined down to lower temperatures than has previously been possible. The temperature dependence of the intrinsic concentration differs from that calculated for the band model. It is suggested that tails of states on the band edges may be responsible for the discrepancy.
