If we assume a system with an anodic overpotential, the variation of n as a function
of current density:
1. at low fields is linear 2. at higher fields, it follows Tafel's law
Obtain the range of current densities for which the overpotential has the same value
when calculated for 1 and 2 cases (maximum relative difference of 5% compared to
the behavior for higher fields).
To which overpotential range does this correspond?
Data: i = 1.5 mA cm², T = 300°C, B = 0.64, R = 8.314 J K1 mol-1 and F = 96485 C mol-1.
