At low current densities (𝐼 ≪ 𝐼 0,𝑛 for all n), all reaction steps will be in the linear region of BV kinetics. As in the case of a one-step reaction, there are infinitely many combinations of αn and I0,n which give the same value of 𝑅 𝑐𝑡,𝑛 0 , so kinetic measurements within the linear region cannot discern the values of α or I0, nor whether the reaction is one-step or multi-step. At high current densities (𝐼 ≫ 𝐼 0,𝑛 for all n), all the reaction steps will be in the Tafel region with an apparent Tafel slope of:
