12.下列反應式均列有該反應之$\DeltaH_{298}^{0}(\mathrm{J})$及$\DeltaS_{298}^{0}(\mathrm{J\K}^{-1})$值，試問何種反應在任何溫度下都不可能進行自發反應？

(A)\(\mathrm{H}_2(\mathrm{g})+\mathrm{Cl}_2(\mathrm{g})\rightarrow2\mathrm{HCl}[\DeltaH_{298}^0=-185,\DeltaS_{298}^0=141]\)
(B)\(\mathrm{NH_4Cl(s)}\rightarrow\mathrm{NH}_3(\mathrm{g})+\mathrm{HCl(g)}\)\([\DeltaH_{298}^{0}=176,\DeltaS_{298}^{0}=284]\)
(C)\(2\mathrm{SO}_2(\mathrm{g})+\mathrm{O}_2(\mathrm{g})\rightarrow2\mathrm{SO}_3(\mathrm{g})[\DeltaH_{298}^0=-198,\DeltaS_{298}^0=187]\)
(D)\(3\mathrm{O}_2(\mathrm{g})\rightarrow2\mathrm{O}_3(\mathrm{g})\)\([\DeltaH_{298}^{0}=286,\DeltaS_{298}^{0}=-137]\)
