ON THE PROBABILISTIC CHARACTER OF CHEMICA L-EQUILIBRIA CALCULATIONS IN CONCERN WITH NEBULAR MATTER CONDENSATION

Theoretical problems arising from the application of chemical thermody namics methods in the mathematical modeling of a chemical system of lo ng durability are considered. The probabilistic interpretation is carr ied out as a result of stochastic variations of external effects provi ding the compensation of experimental data errors in a system. The con cept allows to estimate the probability of coexistence of concurrent e quilibrium phases in terms of thermodynamics. The results of stochasti ng modeling of equilibrium condensation of nebular matter are presente d. Oscillating character of temperature dependence of forsterite and e nstatite masses is established.
