Abstract:

The X-Y pulsed measuring system developed at the Naval Research Laboratory was modified for the study of electrochemical systems. It was possible to determine the electrokinetic parameters of fast reaction steps. Kinetic equations were derived which are applicable to the X-Y pulsed measuring system. An investigation of the H reaction on Pt in acid solution resulted in a quantitative separation and determination of solution resistance, charge on the double layer, and the dischargeionization reaction step. Experimental results indicated that H atoms were associated with the Pt surface in three ways some are weakly bonded to the surface others are strongly bonded and the residue of H atoms are absorbed in surface layers of Pt. The kinetic analysis showed that only a small number of H atoms are in rapid equilibrium with H2 gas at the equilibrium potential. Author
