Tafel Plots Normalized with Respect to the Surface Concentration of EAC 

On elimination of anodic or cathodic exponential terms from Eq. (5.5), we shall obtain respectively  

To obtain the NTP in case of consecutive transfer of several electrons, a more complicated kinetic equation (5.22) must be first simplified. This is possible to do having made the assumption about which of the steps, (Eq. (5.9) or (5.10)), determines the rate of the process. If it is transfer of the first electron, the condition that 01 02 satisfied, and the term of Eq. (5.22) with i can be rejected. Further, 

The NTP expressions are found in the analogous way when the rate-determining step is transfer of the second electron to EAC, that is, when io2 oi- 

Several properties of the equations obtained should be mentioned. It is natural that they contain kinetic parameters of the rate-determining step only. However,
