Nonlinear voltage profiles and violation of local electroneutrality in ordinary surface reactions

The voltage profiles and local electroneutrality in ordinary surface reactions were studied. The study was based on producing nontrivial voltage profiles by ordinary surface reactions. The violation of local electroneutrality was considered via the Poisson's equation implying a nonzero bulk charge density. For the slow steady reactions, in the planar lead-acid cell under study, linearly varying electric field and density gradients were produced. As a result of which the quadratic variation in the voltage profile was obtained, whereas the volume charge density was nonzero and uniform.
