In this work, reversible microdisk electrode reactions with coupled first-order homogeneous chemical reactions are discussed by means of the equivalence between the recombinated steady state diffusion equations and the Laplace transformed tran-sient diffusion equation of electrode reactions. First, general solution for transient diffusion equation of reversible microdisk electrode reactions is derived with “uni-form concentration” approach which is acceptable if D_O is close to D_R. And then, expressions for steady state current of CE, EC, EC' and ECE reactions at microdisk electrode are derived with the help of that general solution.
