Summary
-
1.
A study has been made of the effect of temperature on the catalytic hydrogen waves produced by pyridine in buffer solutions. Calculations have been made of the rate constants for the reaction of pyridine with various proton donors: boric acid, veronal, the hydroxonium ion, and water, at temperatures of 15, 25, 35, and 45° (see table). The activation energies of the corresponding protolytic reactions have been calculated from the temperature dependence of the rate constants.

2.
On the basis of a study of the catalytic waves in solutions of different ionic strengths, it has been shown that the apparent increase in the pyridine protonation rate constant observed on raising the pH of the solution is caused by an effect of the diffusional part of the electric double layer on the kinetics of the ionic chemical reactions occurring in the vicinity of the electrode surface.
