摘要:
简要说明ΔG与ΔrGm作为方向性判据的区别。其中ΔG判据的适用条件是封闭系统的等温等压过程;而ΔrGm判据是ΔG判据应用于化学反应系统时的进一步推演。ΔrGm代表反应系统在某一时刻的势函数, 作为方向性判据, 只需要W'=0, 而不需要等温等压条件。
关键词: &Delta, G判据, &Delta, rGm判据, 吉布斯函数
Abstract:
The difference between ΔG and ΔrGm as direction criteria was briefly described. The ΔG criterion is applicable to the isothermal and isobaric processes of the closed system; however, the ΔrGm criterion is the further deduction of application of the ΔG criterion in chemical reaction system and represents the potential function of the reaction system at a certain time. ΔrGm as the direction criteria requires only W'= 0 instead of the isothermal and isobaric conditions.
Key words: ΔG criterion, ΔrGm criterion, The Gibbs function
