In this work, we present theoretical results in cyclic staircase voltammetry of a surface catalytic mechanism that features reversible chemical step, the so‐called “surface catalytic EC_rev’ mechanism”. We consider specific surface regenerative mechanism, in which both of the electro‐inactive substrates are present in large excess in electrochemical cell from the beginning of the experiment. The chemical reversibility brings at this mechanism more complexity in respect to the features of well‐elaborated surface catalytic EC’ mechanism coupled with chemically irreversible regenerative reaction. As we present plenty of simulated cyclic voltammograms, we also propose methods to get insight to kinetics and thermodynamics parameters relevant to chemical regenerative step. The elaboreted results can be important in analysing the kinetics and thermodynamics of many drug‐drug and drug‐DNA interactions, for example. In addition, with the results elaborated in this work we can access relevant information about the chemistry of important lipophilic enzymes studied in protein‐film voltammetry set up.

循环楼梯伏安法条件下与可逆化学反应有关的表面催化机理的理论分析

在这项工作中，我们以循环阶梯伏安法介绍了具有可逆化学步骤的表面催化机理的理论结果，即所谓的“表面催化EC_转速”。“机制”。我们考虑了特定的表面再生机理，从实验开始，电化学电池中两种电惰性底物都大量过量存在。考虑到精心设计的表面催化EC'机理与化学不可逆的再生反应相结合的特性，化学可逆性使该机理更加复杂。由于我们提供了大量的模拟循环伏安图，因此，我们还提出了一些方法来深入了解与化学再生步骤有关的动力学和热力学参数。例如，详尽的结果对于分析许多药物-药物和药物-DNA相互作用的动力学和热力学非常重要。此外，
