Abstract
It was found that the kinetic behavior of the electrodic interface alp ha-AgI/I2(g), graphite is strongly dependent on the pressure applied t o the contact. The voltammetric response at low contact pressure shows an anodic peak but no cathodic one, whereas at higher pressures the o pposite is found. The transition between the two cases is obtained at an applied pressure of about 10-12 kg cm-2. An explanation is given fo r the behavior at low contact pressure, based on the formation of a re sistive effect due to the products of the anodic reaction.
