Electrochemical aspect of kinetic processes

We have previously mentioned that the activation energy value can be changed when there is movement of charged species. In such a case, an electrochemical 

The rate V of this reaction is defined as the number of electron grams dn extracted from the reducing agent during dt and per surface unit, therefore  

Suppose are the energy values that define the activation energies 

The idea that a and p are functions of time is based on the fact that the surface potential value, and therefore the curve V = f(x,t), changes during the shift towards equihbrium. Therefore, the coefficients a and p which describe this curve, may from now on be associated with such an evolution type. 

Given the extent to which these coefficients affect kinetic parameters, we will clarify them for two particular cases that of an abmpt junction in a closed medium, and then in an open medium - the latter being typical of adsorption.
