Abstract
Results of the Equilibrium between Liquid CoPPer and CO-CO2 Gas Mixtures． In our lst report， we reported the experimental resul宅s of the equilibrium between．1iquid coPPer and COCO2 gas mixtures．1：n the present paper， the effect of the temperature upo亘the equilibrium co：nstan，t and the relation between the activity and the conce：ntration of oxygen， in， 1iquld copper have been determined． The results obtai：ned are as follows； q(inZ-Cu)＋CO＝COゴ； 1・9瓦一1・9畿。一10罪一382・ 311．3 ・〔0％ユ 109αo＝109〔0％〕一 T Combin，ing these results with the know：n thermodyn．amical data， the partial pressure of oxygep， on liquid copper saturated with oxyge：n has been estimated as follows： po2＝3．28×10-5atm． at 12000．
