Berzins-Delahay equation
In electrochemistry, the Berzins-Delahay equation is analogous to the Randles–Sevcik equation, except that it predicts the peak height ( i p {\displaystyle i_{p}} ) of a linear potential scan when the reaction is electrochemically reversible, the reactants are soluble, and the products are deposited on the electrode with a thermodynamic activity of one. i p = 0.6105 A C ( n F ) 3 D v R T {\displaystyle i_{p}=0.6105AC{\sqrt {\frac {(nF)^{3}Dv}{RT}}}} A {\displaystyle A} = electrode surface area in cm2 C {\displaystyle C} = concentration of the reactant in mol/cm3 n {\displaystyle n} = stoichiometric number of electrons exchanged in equivalents/mol F {\displaystyle F} = Faraday constant in C/equivalent D {\displaystyle D} = Diffusion coefficient of the reactant in cm2/s v {\displaystyle v} = scan rate in V/s R {\displaystyle R} = Gas constant in J/molK T {\displaystyle T} = temperature in K Despite the fact that this equation is derived under very simplistic assumptions, considering the complex phenomenon of nucleation, the Berzins-Delahay equation often makes good predictions of i p {\displaystyle i_{p}} .
