Mass Transport of Chemically Interacting Particles

Chemical interactions taking place in the system under discussion can be written in the following way  

Concentrations of species indicated in the square brackets are functions of the coordinate x and time t. In solving the diffusion problem, Eick s second law with 

Having in mind the fact that it is only the particles containing metal that can reduce and that ligand is regarded to be electrically inactive, initial and boundary conditions are specified by Eqs. (3.7)-(3.9) in which the value c is replaced with concentration 

Two main conclusions follow from the aforementioned fact  

Let us consider another system, which also contains protonated ligand forms. We shall assume that they are unable to form coordination bonds with M ions for the reason that a proton, when bound to the donor atom of ligand, blocks the free electron pair. For the sake of simplicity, we shall limit ourselves to only one of such particles, namely to EH . Then, the above-listed chemical interactions Eqs. (3.16) and (3.17) are to be supplemented with the following reactions L -H H EH and H -I- OH H2O. An analogous analysis shows that the

Next chapters acquaint readers with the theory and common experimental practice for studying electrochemical reactions of metal complexes. Regularities of mass transport of chemically interacting particles considered in Chapter 3 serve for determining the surface concentrations of complexes and ligands. Furthermore, these data make it possible to reveal the peculiarities of electrochemical processes (Chapter 4) and form the basis for quantitative modeling of electrochemical processes (Chapter 5) and determining their mechanism (Chapter 6).
