摘要
用量热计测得碳酸二苯酯的标准燃烧焓ΔcH0m =- 6 138.6kJ mol,与理论计算值的绝对误差仅为 5kJ mol,相对误差为 0 .0 8%。从样品燃烧的温度变化曲线可判断实验结果是可靠的。
The standard combustion enthalpy measured by calorimeter is -6138.6kJ/mol. In comparison with calculated value, the absolute error is only 5kJ/mol and the relative error is 0.08%. By analyzing the temperature curve of sample combustion, it shows that the experimental result is accurate and reliable.
