3.以奧士瓦黏度計，如圖(二)，量測試樣液體之黏度時，下列敘述何者錯誤？ (A)量測時，注入液體高度須高於A點(B)量測時，須計算由B點升至A點所需時間(C)需要量測已知黏度係數的參考物液體通過標線所需時間(D)奧士瓦黏度計需置入恆溫槽中

12.a下列反應式均列有該反應之\(\Delta H_{298}^0(J)\)及\(\Delta S_{298}^0 (\text{J K}^{-1})\)值，試問何種反應在任何溫度下都不可能進行自發反應？(A)\(\text{H}_2(\text{g})+\text{Cl}_2(\text{g}) \rightarrow 2\text{HCl}[\Delta H_{298}^0 = -185, \Delta S_{298}^0 = 141]\)(B)\( \text{NH}_4\text{Cl(s)} \rightarrow \text{NH}_3\text{(g)} + \text{HCl(g)} [\Delta H_{298}^0 = 176, \Delta S_{298}^0 = 284] \)(C)\(2\text{SO}_2(\text{g}) + \text{O}_2(\text{g}) \rightarrow 2\text{SO}_3(\text{g}) [\Delta H_{298}^0 = -198, \Delta S_{298}^0 = 187]\)(D)\(3\text{O}_2(\text{g}) \rightarrow 2\text{O}_3(\text{g}) [\Delta H_{298}^0 = 286, \Delta S_{298}^0 = -137]\)
