Reactions of chlorine with liquid metals. 2. Lead
The reaction of molecular chlorine with solid and liquid lead surfaces was studied by modulated molecular beam-mass-spectrometric methods in the temperature range 300-900 K and at equivalent chlorine pressures between 5 x 10/sup -6/ and 5 x 10/sup -4/ torr. The only detectable volatile reaction product was PbCl/sub 2/. Up to the melting point of lead (601 K) the apparent reaction probability did not exceed 10/sup -3/. For the liquid phase, production of PbCl/sub 2/ increased rapidly with increasing surface temperature and the reaction was nonlinear with respect to chlorine equivalent pressure. A reaction model was developed which takes into account solution-diffusion of chlorine from the surface into the liquid and production of PbCl/sub 2/ by parallel Eley-Rideal and Langmuir-Hinshelwood mechanisms.
