Voltage dependencies of slow (ms) chemical relaxations.
The exponential-relaxation rates (rate constant k) of relatively slow (ms) chemical reactions may change with applied potential. Three general cases are described which, by their dependencies on an externally applied voltage, should be experimentally separable. They are processes due to (1) permanent dipoles entirely in the field - - (d In k)/d V proportional, variant V(2); (2) surface charge change - - (d In k)/d V proportional, variant V; and (3) charge transport - - dk/d V proportional, variant V (or a delay proportional to 1/V. The general analysis presented may be useful in analyzing biological electrical processes.
