Homogeneous nucleation in thermal dust-electron plasmas
1Mechnikov Odessa National University, Odessa 65026, Ukraine.
Abstract:
The homogeneous nucleation in the dust-electron plasma, which is formed in the zone of metal powder combustion products in the premixed laminar two-phase flame, has been studied. The classical nucleation theory has been used to determine the free energy and the critical radius of the nucleus. The influence of nucleus charging as a result of interaction between the nucleus and the electronic component of the plasma on the free energy has been determined. The dependence of the nucleus' critical radius on the plasma temperature and number density of the plasma's dust component has been determined. The proposed theoretical model shows that nucleation in the thermal dust-electron plasma is a self-consistent process, which is opposed to changing of the plasma's disperse structure.

Homogeneous Equilibria for Gaseous Reactions
For gas-phase reactions, the equilibrium constant may be expressed in terms of either the molar concentrations (Kc) or partial pressures (Kp) of the reactants and products. A relation between these two K values may be simply derived from the ideal gas equation and the definition of molarity. According to the ideal gas equation:
