The total for this quantity is proportional to the sum of two hyperbolic sine functions at the Helmholtz limit when the symmetry factor is one-half, but is instead logarithmic when the Chang-Jaffe boundary conditions hold.

If this quantity is zero, then the difference between the peaks in a CV experiment is just 57 over n. The Stern-Geary equation explains how this quantity arises from polarization resistance. This quantity multiplies two different charge transfer coefficients in both the positive and negative exponentials of an equation that gives the (*) current density as a function of the exchange current density. This quantity symbolized eta increases linearly with the log of the current on a Tafel plot. The Butler-Volmer equation accounts for it being nonzero. For 10 points, name this quantity neglected by the Nernst equation, which is the number of volts beyond equilibrium at which a redox reaction is actually observed.
