Abstract
<p style="margin: 0cm 0cm 8pt; line-height: 150%;"><span lang="EN-GB">Three fast and reversible electrode reactions that are connected by two reversible chemical reactions that are permanently in the equilibrium are analysed theoretically for square wave voltammetry. The dependence of peak potentials on the dimensionless equilibrium constants of chemical reactions is calculated. The influence of the basic thermodynamic parameters on the square wave voltammetric responses is analysed.</span></p>
Highlights
Multistep electrode processes appear in electrochemistry of many organic compounds [1,2,3,4,5,6,7,8,9]
A theory of three electrode reactions that are coupled by two reversible chemical reactions is developed for square wave voltammetry under equilibrium conditions
Theoretical models of ECECE are developed for reversible electrode reactions and totally irreversible chemical reactions in cyclic voltammetry [16] and chronoamperometry [17,19]
Summary
Multistep electrode processes appear in electrochemistry of many organic compounds [1,2,3,4,5,6,7,8,9] Some of these mechanisms include chemical steps [10,11,12,13,14,15]. In this communication, a theory of three electrode reactions that are coupled by two reversible chemical reactions is developed for square wave voltammetry under equilibrium conditions. Theoretical models of ECECE are developed for reversible electrode reactions and totally irreversible chemical reactions in cyclic voltammetry [16] and chronoamperometry [17,19]
