The kinetics of the. reaction, of dilute hydrochloric acid with cadmium metal, molded, electroplated on brass, and dipped on brass, have been investigated by means of calibrated conductance measurements. The effect of annealing molded cadmium samples was to reduce the corrosion rate. Changing the speed of spinning the cylindrical sample increased the rate with increase in rotational velocity, up to a constant value at high velocities. The reaction rate at three acid concentrations and at three temperatures were determined. The activation energy is small, between one and two kilocalories per mole of cadmium reacting. In all cases the reaction was zero order over 90 percent of the reaction process. The rate controlling1 step has been estimated as that of diffusion through the layer surrounding the cadmium surface. 3.8.4
