試題詳解

8. All of the following are spontaneous reactions that proceed to the right. Standard reduction potentials at 259C are provided for some half-cell reactions. Based on this information, rank the relative strengths of H⁺, Ag⁺ , Cd²⁺, Cu²⁺, and Zn²⁺ as electron acceptors (oxidizing agents) at 25℃. (4%)
(A) Cu²⁺ ＞ H⁺＞Ag⁺ ＞ Cd²⁺＞Zn²⁺
(B) Ag⁺＞ Cu²⁺＞H⁺> Cd²⁺＞Zn²⁺
(C) Zn²⁺＞ Cd⁺＞Ag⁺＞ Cu²⁺＞H⁺
(D)Zn²⁺＞ Cd⁺＞ H⁺＞Ag⁺ ＞ Cu2⁺
(E) There is not enough information to deduce their relative oxidative strengths.
