利用状态函数法推导气体化学势的讨论

摘要

物理化学经典热力学理论中,化学势是最重要的热力学函数之一,化学势对于理论研究或是实际应用都具有极其重要的意义.同吉布斯函数一样,化学势没有绝对值,所以建立化学势解析表达式就必须选择一个标准态作为计算的基准.气体化学势及其标准态不易理解,本文在规定标准态、确定气体的状态和运用热力学基本定律的基础上,利用状态函数法推导了气体的化学势.%Chemical potential is one of the most important thermodynamic functions in classical thermodynamic theory. Chemical potential is of great importance for theoretical research and practical application. As the gibbs function, the chemical potential has no absolute value,and a standard state is chosen as the basis for the calculation of the chemical potential analytic expression. The gas chemical potential and standard state are not easy to understand. The chemical potential of the gas was derived by state function method for determining the state of gas and the fundamental law of thermodynamics.
