Abstract
The thermal decomposition of CuBr2·2NH3 has been examined at the constant temperature, about 220°C. Copper(II) was reduced to copper(I), when bromine gas was found as one of the decomposition products, indicating that bromide anion may be the reducing agent for copper(II). The decomposition reaction of CuBr2 has been investigated by measuring the weight loss under the condition of the constant temperature. In a closed system, the reaction, CuBr_2(s)\leftrightarrowsγ-CuBr(s)+\frac12Br_2(g) attained to equilibrium, and ΔG° for this reaction was determined in the range from 160°C to 220°C to be given by the equation, ΔG°(cal.)=1.10×10^4-19.3 T (160°C–220°C). While the pressure of bromine gas was kept zero, CuBr2 decomposed following a first-order rate law in the beginning of the decomposition, and the activation energy was found to be 25.4 kcal/mol.
