Reaction Dependent on Potential Only

For systems involving single reactions, it is convenient to incorporate the interfacial equilibrium potential Vb,M into the effective rate constant as 

The Faradaic current response to a potential perturbation can be expressed as  

Equation (10.9) corresponds to equation (10.3) with only the first term of the expression. 

The charge-transfer resistance is defined in terms of kinetic parameters as 

The charge-transfer resistance is a function of the steady-state potential V. Equation (10.5) can be expressed in terms of the Tafel slope
