Application of the reaction order approach using CV or DCV

In practice, the values of v necessary to hold Rx or Rj at a constant value, most commonly equal to 0.500, are determined and defined as vc, i.e. f o.s when the peak current ratio is held constant at 0.500. Under these conditions, z can conveniently be determined by the logarithmic relationship 

the reaction order approach involves the analysis of plots or correlations of logi c vs. log CA or log Cx in order to determine Raib and Rx from which rate laws can be formulated for the process in question. In the event that the rate-determining step does not change as the concentration of reagents is changed, both z and x are obtained as the slopes of linear plots or correlations. This is the case for the simple reaction mechanisms such as those illustrated in Table 16. Any curvature in the log—log plots indicates complications which could be due to
