※ 引述《FLYINGNIGHT (阿森)》之銘言： : 1.Arrange molecular the following substances(1 mole each) in order of : increasing entropy at 25度C: a.Ne(g) b.SO2(g) c.Na(s) d.NaCl(s) e.H2(g) 怪怪的，我記得的判斷方法跟你一樣 : 2.A student placed a few ice cubes in a drinking water. A few minutes later : she noticed that some of the ice cubes were fused together. Explain 把一些冰塊放在你要喝的水的中，一會兒有些冰塊變成兩塊黏在一起， 變一大塊。 : 4.下列何者是零級反應: : a. thermal isomerization of cis-stilbene to trans-stilbene : b. enzyme oxidation of glucose to gluconic acid : c. decay of radioactivity of 60Co : d. decay of triplet excited C60 to ground state : e. none of the above a.零級反應速率r = k (constant) 不會變，跟反應物濃度沒有關係， 只有第一個跟反應物濃度沒有關係，只是一個分子自己在互變。 不過話是這樣說，實際狀況還蠻懷疑的XD b.氧化跟反應物濃度有關係的可能性很高 : 5.the standard free enery of formation of CS2(l) is 65.27 kj/mol at 298K. : this neabs that at 298K. : a.CS2(l) will not spontaneously from C(s)+2S(s) : b.CS2(l) is thermodynamically unstable : c.CS2(l) is thermodynamically stable : d.No catalyst can be found to decompose CS2(l) into its elements : e.CS2(l) has negative entropy : 答案是E 不過不是很確定 我只知道d是錯的.. 感覺應該 b或c是答案.. entropy 有負的嗎??? 我記錯了嗎? 不過感覺這題好像是多選題的感覺 a c 的樣子 : 6.Hydrogen can be made from fossil fuels in as series of two catalyzed : reactions.One of these reactions,the re-forming reaction,is : a.Zn+2HCl→ZnCl2+H2 : b.CH4+H2O→CO+3H2 : c.Cu(s)+2H+→Cu2+ +H2 : d.CH3OH→2H2+CO : 有去查re-forming 很像是再生 不過這題還是不會 答案看到是b re-forming不是指催化劑的再生嗎??? : 7.Which of the fllowing are heteogeneous alloys? 不同相的合金，應該就C了吧 --
