✦ Synopsis

As there are many chemical reactions in dispersed hetero-In this paper, the expressions of Gibbs energy change, enthalpy geneous systems, such as in chemistry, chemical industry, change, entropy change, and equilibrium constant for chemical biology, and material field, it is very important to study the reactions in dispersed heterogeneous systems are derived using thermodynamic theory for chemical reactions in dispersed classical thermodynamics theory. The thermodynamical relations heterogeneous systems.

for the same reaction system between the dispersed and the block

There are many reported studies on the thermodynamical state are also derived. The effects of degree of dispersion on therproperties of disperse heterogeneous systems, but only a few modynamical properties, reaction directions, and chemical equilibdeal with chemical reactions. Patrilyak (5) discussed the ria are discussed. The results show that the present equation of thermodynamics of reversible formation of a solid comthermodynamics for chemical reactions is only a special case of the above-mentioned formulas and that the effect of the dispersity pound AB from a solid component A and a gasous compoof a heterogeneous system on the chemical reaction obeys the Le nent B and presented a comparative analysis of the thermo-Chatelier principle of movement of equilibria. ᭧ 1997 Academic Press dynamical properties of the matter in bulk and in dispersed Key Words: heterogenous system; dispersed system; chemical phases, but the results are not general.
