摘要: 用自行研制的具有恒定温度环境的新型反应热量计,以0.01mol·L-1H2SO4溶液为量热溶剂,分别测定了[2CsCl(s)+CuCl2·2H2O(s)]和Cs2CuCl4的溶解焓,根据Hcss定律设计了一个热化学循环,求出了Cs2CuCl4的标准生成焓,推荐其值为;ΔfHmθ(Cs2CuCl4,S,298.2K)=-1129.04kJ·mol-1. |

Abstract: The standard enthalpy of formation of Cs2CuCl4 was determined by a new model isoperibel reaction calorimeter. The calorimetric solvent is an acid solution consisting of 0.01mol L-1 H2SO4 A thermochemical cycle was designed to determine the enthalpy. According to the results obtained, the value ΔfHmθ(Cs2CuCl4, s, 298.2K)=-1129.04kJ·mol-1 was recommended. |
