Description

The emf measurements of the following galvanic cells have been carried out to determine the standard free energy of formation of Bi2O3(s) and the thermodynamic quantities of liquid Tl-Bi alloys:<BR>(This article is not displayable. Please see full text pdf.) <BR>The standard free energy of formation of Bi2O3(s) are determined as follows:<BR>(This article is not displayable. Please see full text pdf.) <BR>The activities of both components in liquid Tl-Bi alloys at 850 and 950 K deviate to negative from Raoult’s law over the whole concentration ranges and agree well with the previous results. The γ°Bi and γ°Tl values are estimated to be 0.031 and 0.17 at 850 K and 0.037 and 0.20 at 950 K, respectively. The α function of bismuth against NBi does not show a constant value, suggesting no regular solution behavior in the system.<BR>The free energy of mixing at 850 K shows negative values than ΔGid, and the peak value of ΔG is −9.3 kJ/mol at about NBi=0.46. The heat of mixing also shows negative values. The peak value of ΔH is −4.4 kJ/mol at about NBi=0.40.
