状态函数法是化学热力学的基本方法,在热力学的有关计算中要经常用到它。本文将通过一些实例对其在各类过程中的运用加以分析与归纳,仅供参考。 在化学热力学中,我们将那些只与物系的状态有关的物理量称为状态函数。内能是物系的状态函数之一。 热力学已经证明:在无外场存在时,封闭物系中各物质的量确定之后, The state function method is the basic method of chemical thermodynamics and is often used in the calculation of thermodynamics. This article will use some examples to analyze and summarize its use in various processes, for reference only. In chemical thermodynamics, we refer to those physical quantities that are only related to the state of the system as the state function. Internal energy is one of the state functions of the system. Thermodynamics has proved that when there is no external field, the amount of each substance in the closed system is determined,
