| Abstract: | Formation thermodynamics has been investigated for the vapor complexes PrAl_xBr_(3x 3) by quenching experiments which were done within the temperature range from 632 to 833K and pressure range from 0.030 to 0.25MPa for about 6hrs required for balanced reaction. The results showed that the complex PrAl_3Br_(12) is the only one produced from the reaction of praseodymium bromide with vaporized aluminum bromide dimer under the experimental conditions, of which the equilibrium constants of reaction are calculated from experimental data. Based on the stability constants obtained from experiments, the changes of enthalpy and entropy in reaction can be obtained by way of least square. |
