摘　　要：通过理想气体反应等温方程和标准态转换,给出了摩尔反应热力学能、摩尔反应焓、标准摩尔反应亥姆霍兹函数和标准摩尔反应吉布斯函数在等温、等容条件下使用不同标准态时的另一组转换关系式,加上已经给出的在等温、等压条件下使用不同标准态时几个热力学函数间的转换关系式,使这类关系式更全面、完整。对这些关系式的应用条件以及在热化学和基元反应速率理论中的某些热力学函数关系进行了讨论。A series of new relationships among standard molar thermodynamic energy,enthalpy,Helmholtz and Gibbs functions in the chemical reactions at constant temperature and volume using different standard states is established,based on the transform of the isotherm equation of chemical reactions in perfect gases combined with standard states.As a complementary discussion on the relationships of thermodynamic functions at constant temperature and pressure using different standard states,it makes all the relationships more self-consistent and rational.Furthermore,the application conditions of theses relationships are suggested.Finally,some relationships of thermodynamic functions in thermochemistry and rate theory of elementary reaction are given.
