where a≡ −∂C/∂u is the thermodynamic capacitance matrix or the negative of the entropy Hessian hik = ∂2ρs/(∂ci ∂ck). Eq. (91) contains two symmetric matrices, a and L. We shall consider a variational formulation for this equation in terms of potentials. We shall show...
They include the constant capacitance (CCM), triple-layer (TLM), and modified triple-layer, Stern variable surface charge-variable surface potential (VSC–VSP), generalized two-layer, and the one-pK models. Differences in the surface complexation models lie in the descriptions of the electrical ...
Essentially, the differential rate law determines how long it takes for the chemical reaction to go from all reactants to all products. It is also important to understand how to find the rate constant. In order to do so, the integrated rate law can be used. The integrated rate law ...

As it turns out, the product of a resistance and a capacitance has units of seconds. If we define w0 = 1 / (R * C) we get: H(jw) = 1 / (jw/w0 + 1) Multiplying numerator and denominator by w0 gives: H(jw) = w0 / (jw + w0) We are interested in the frequency amplitu...

The shift of oxygen potential under polarization was proved indirectly by chemical capacitance of a film electrode [15] and more directly by spectroscopic approaches such as Refs [16–19]. Thus, the reaction is driven by chemical driving force. Discussion on chemical versus electrochemical reaction ...
