Storage of matter

Each compartment is considered now as a combination of an infinitesimal resistance and an infinitesimal capacitance element for each kind of the penetrating ions. Whereas the resistance of the medium is assumed to be a joint property of the material and electric interactions of the ion with the medium, separate capacitances are introduced for the storage of matter and electric charge one material capacitance for each kind of ions i = 1,2,. .. and a common electric capacitance for the net amount of electric charge. If only one kind of ion with a valency z. were present, the network for a single compartment would then be given by... 

The relationships are very simple in the stationary state, since then all individual reaction rates (fluxes) are the same, i.e. there is no storage of matter at any locus of the chain. Then Ttum is the uniform overall reaction rate H.
