熵增大的放热反应的不可逆程度与温度的关系

Temperature dependence of irreversible degree of evolved heat reaction with entrop y increase

运用不可逆过程热力学中关于熵流和熵产生的概念,分析讨论了一类熵增大的放热反应的不可逆程度与温度的关系,说明了为什么应该用diSdξ作为化学反应不可逆程度的判据.

Applies the concepts about entropy f lux and entropy produced in irrevers ible thermodynamics,ana-lyzes and discusses the relationshi p of temperature and the degree of irr eversibility for one kind of exothermic reaction with entropy increase,and explains why we should use it as the criterion for degree of irreversibility of the chemical reaction.
