Ammonium nitrate product-favpredly dissolves in water at room temperature and
the process causes the solition to become quite cold
Which of the following is not true about the dissolution of ammonium nitrate?
(A)the process is exothermic
(B)the solubility will be greater in warm water
(C)delta S for the reaction is negative
(D)all solution of ammonium nitrate are supersaturated
答案是A，我也觉得C也错耶大家觉得呢
我的想法:Product-favoredly→自发→S>0

你之前是不是化合物打错自发是delta G<0 定义看清楚就没问题了

是呀之前字打错被发现了哈哈delta G=H-TS 答案表示delta S是负的(+)-(+)(-)→delta G如果照答案那是>0

看到那句就直接否定你真不好意思 原来你有推过我仔细看完 应该是ACD叙述错 B叙述正确

只有B是对的其他选项都错

谢谢BiGiLa和begolong两位大大~
