Bourdon Gauge Determination of Chemical Equilibrium in the Ge-CI₂ System

Bourdon gauge pressure measurements of samples of GeCl4(g) and GeC14(g) plus Ge(s) have been made in the temperature range 300°1300°K The pressure change of pure GeCl4 as a function of temperature indicates that it does not dissociate up to 1300° The pressure vs. temperature behavior of GeCl4 (g) plus Ge (s) is described by the equilibrium [formula ommited> The standard enthalpy, ΔH°, and entropy, ΔS°, of reaction at 723°K were found to be 34.9 kcal and 46.7 eu, respectively. © 1965, The Electrochemical Society, Inc.
