Homogeneous or Heterogeneous Chemical Reaction as Rate-Determining Step

Homogeneous or Heterogeneous Chemical Reaction as Rate-Determining Step 

According to Vetter [11, 72], an electrochemical process can also be controlled by a chemical reaction in the bulk (homogeneous reaction) or at the interface (heterogeneous reaction). The corresponding expressions for the real and imaginary components of the impedance are presented for both cases in the paper by Vetter [11].
