Abstract: The diffusional CrevECirrEC′ mechanism represents the first comprehensive electrochemical framework capable of unifying virtually all common mechanistic electrode reactions within a single theoretical platform. By integrating reversible chemical pre-equilibrium, sequential electron-transfer steps (Crev), irreversible chemical transformation (Cirr), and catalytic regeneration (C’), this mechanism encompasses numerous classical limiting cases including E, ECirrE, CrevE, CrevECirr, EC′, ECirrrE, ECirrEC′, and related multistep systems. For the first time, this work provides a rigorous mathematical solution of the CrevECirrEC′ mechanism under cyclic voltammetry conditions, combining Butler–Volmer kinetics with diffusional mass transport and homogeneous chemical kinetics. The importance of this approach lies in its unprecedented versatility: rather than developing separate mathematical treatments for individual mechanisms, the CrevECiEC′ framework serves as a universal mechanistic parent model from which simpler systems naturally emerge through parameter adjustments. This establishes the mechanism as a foundational tool for mechanistic interpretation, kinetic evaluation, and simulation of complex electrochemical processes across chemistry, biomedicine, catalysis, and energy sciences. To maximize accessibility and educational value, the model is also implemented for the first time as a freely available Mathcad simulation protocol, enabling researchers, students, and educators to perform advanced cyclic voltammetric simulations through an open computational platform. This work not only expands theoretical electrochemistry but also provides a practical and highly adaptable simulation environment for future mechanistic exploration.
