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.
