Reaction graph, electrical analog

A quantitative theory of the reaction route graphs based on electric analogy was developed by Hie Fishtik and Ravindra Datta. 

Fig. 4.23 Electrical analog of the reaction graph in Fig. 4.22. (From S.A. Viiekar, i. Fishtik, R. Datta, The steady-state kinetics of paraiiei reaction networks, Chem. Eng. Sci. 65 (2010) 2921-2933. Copyright 2010 Eisevier).

The analogy with electric circuits made earlier is certainly not an obvious one. and in the works of Vorkenshtein and Gordshtein (2,3), a requirement exists that the kinetic graph for noncataly tic reactions contain a nuU vertex with a concentration equal to 1. For catalytic reactions the role of the null vertex is that of a free catalytic surface.
