雖然物理化學很像普通化學的進階版，但寫題目還是困難重重啊~ 希望大家不吝賜教，非常非常感謝!!! 第1題 : How many components has a mixture of water and deuterium oxide in whi ch the equilibrium H2O + D2O->2HDO exists? (A) 4 (B) 3 (C) 2 (D) 1 這題是有關Phase rule的問題，相律真的好難懂啊啊啊! Constituents有3個、方程式一個、各項皆為液相不知道要不要算？ 第2題：In a condensed system of two-component phase diagram containing solid and liquid (Salol and Thymol condensed system), a composition containing a% Sa lol was cooled eventually causing it transforming from a one-liquid phase syst em into a two-phase system (One pure Thymol solid phase and one liquid phase). After equilibrium, the composition of this liquid phase was found to contain b% Salol. Which the following answer is correct to describe the weight ratio o f solid phase/liquid phase? (A) (a-b)/a (B) b/(a-b) (C) (a-b)/b (D) a/(b-a) 這題題目有點長，是eutectic mixture的問題，我不管怎麼算都是b-a/a,不知道錯在哪裡 ... 拜託大家了~~ -- Sent from my Windows --
