熵判据和吉布斯自由能判据

Entropy Criterion Gibbs Free Energy Criterion

本文分析了熵判据和吉布斯自由能判据后认为:在等温等压条件下,总熵判据与过程方式的吉布斯自由能判据完全等价,在等温等压及W≮0的条件下,总熵判据可以判断过程的方向和限度.

This paper analysed the entropy criterion and the Gibbs free energy criterion.At constant T and P, the total entropy criterion is equal to the fashion of process.At constant T, P and W' 0 , the total entropy criterion is used in determining a direction and a limit of a process.
