审稿人给的意见,不太理解,求解释?It is important to note that standard Gibbs energy is not a criterion of spontaneity, and thus, it is not correct to indicate that the dissolution processes are not spontaneous based on dG° values that are always positive. Real criterion is expressed as dG = dG° + RT ln x, with x lower than x at saturation. In this way, dG would be negative if the solution is unsaturated. 1. dG = dG° + RT ln x, with x lower than x at saturation,这句话不太理解,x代表溶质的摩尔浓度,x是小于饱和时的x。2. 为什么说如果溶液不饱和,那么dG就是是负数。本人做的溶解度,一定温度下,溶液达到固液平衡应该就是达到饱和溶液了?查看更多8个回答 . 19人已关注
