自1937年以来，量热法一直被用来测定平衡常数，但以前还没有对各种量热计和方法进行全面的综述。本文报道了定量比较量热仪同时测定平衡常数和热变的能力，确定最佳实验条件的方法，以及评估系统误差和随机误差对用这种方法测定平衡常数和热变的准确性和精密度的影响的方法。(C)2010 Elsevier Inc.保留所有权利。
Calorimetric methods have been used to determine equilibrium constants since 1937, but no comprehensive review of the various calorimeters and methods has been done previously. This article reports methods for quantitative comparison of the capabilities of calorimeters for simultaneous determination of equilibrium constants and enthalpy changes, for determining optimal experimental conditions, and for assessing the effects of systematic and random errors on the accuracy and precision of equilibrium constants and enthalpy changes determined by this method.
