複選題4. 化學電池的自由能變化 $(\Delta G)$ 是反應最大可用的功：$\Delta G = -W_{max}$，對於伏打電池而言，此功即為電功 $-nFE_{cell}$（法拉第常數 $F = 96500$ (C/mol)。已知標準電位： $$ \begin{array}{l} \ln^{+}(aq) + e^{-} \rightarrow \ln(s) \quad E^{*} = -0.21 \mathrm{V} \\ \ln^{3+}(aq) + 2e^{-} \rightarrow \ln^{+}(aq) \quad E^{*} = -0.40 \mathrm{V} \\ \end{array} $$ 關於 $\ln^{+}(aq)$ 的自身氧化還原反應的下列敘述，哪些正確？ (A) 反應式為 $3\ln^{+}(aq) \rightarrow 2\ln(s) + \ln^{3+}(aq)$ (B) 此反應的標準電池電位 $\left(E_{cell}^{*}\right) = 0.19 \mathrm{V}$ (C) 此反應的標準電池電位 $\left(E_{cell}^{*}\right) = 0.61 \mathrm{V}$ (D) 此反應的標準自由能 $(\Delta G^{*}) = -36.7 \mathrm{kJ}$ (E) 此反應的標準電池電位 $\left(E_{cell}^{*}\right) < 0$，屬於非自發性反應
