[Abstract] The maximum and effective energies of an atomic structure equal the sum of their entropic energy components. This summation is performed for systems in equilibrium entropic state and following special rules. The spatial-energy parameter is obtained, which numerically equals the most effective energy in structural interactions. The computational and analytical method for evaluating the solubility and phase formation for complex multicomponent metal systems is developed. The calculation results are quite coherent with the experimental data. The technique based on entropic principles for calculating the activation energy of self-diffusion and volumetric diffusion of atoms in solids is presented.

ENTROPY IN CHEMICAL KINETICS AND PHYSICS Grigory Korablev1 ;

Paper Id: 524
[Abstract] Entropic principles provide the basis for forming functional bonds between many values of chemical kinetics. The equilibrium sum of entropic components of the universal gas constant equal to R/2 has the direct mathematical connection with the geodesic angle tangent. A similar ratio of this parameter is obtained by Arrhenius graphs of reaction rate coefficient dependence on the temperature. When two entropic components move in one format, the equilibrium sum of their energies equals a half of the energy initial value. The established principles are also manifested in other regularities of physical chemistry, for example, by the activation energy in diffusion processes and kinetic energy equation.
