Calculations of Thermodynamic Functions for Gaseous Reaction of 84/70 C_(70)(D_(5h))=C_(84)(D_2)

计算了不同温度下气相反应84／70C70（D5h）＝C84（D2）的热力学函数，讨论了C70（D5h）与C84（D2）之间相互转化的热力学条件；结果表明，温度低于2392K时C84（D2）比C70（D5h）稳定，温度高于2392K时气相中C70（D5h）比C84（D2）稳定；同时给出了气相C84（D2）的标准热力学函数。

The thermodynamic functions for gaseous reaction of 84/70C70(D5h) =C84(D2) at different temperatures are calculated in this paper, and the thermedynamic conditions under which C70 (D5h) changes to C84(D2) are discussed here. Results show that gaseous C84(D2) is more stable than gaseous C70(D5h) as temperature below 2392 K and gaseous C70(D5h) is more stable than C84 (D2) as temperature high than 2392 K. The standard thermodynamic function of gaseous C84 (D2)is also reported here.
