Solutions Containing Non-charged Components

Homogeneous reactions are sometimes accompanied by significant calorification, hence the energy equation should take into account heat evolution in the volume. In the present chapter, we consider processes with no volume calorification, so the assumption of an isothermal solution will be valid. 

The specific molar production rate of an i-th component in the course of a homogeneous reaction is determined by the expression  

Generally, Rf depends on T, p, and the concentration of a component participating in the reaction, for example, a catalyst or inhibitor. 

Heterogeneous reactions occur at a surface, and therefore the specific molar rate is determined by  

Theoretical descriptions of homogeneous and heterogeneous chemical reactions are similar. Transition from one reaction to another can be carried out by using the formula
