Exhibit 17-1
The following question(s) pertain to the electrochemical system pictured below. Cell A contains an aluminum electrode and a 1 molar solution of Al(NO₃) ₃. Cell B contains an iron electrode and a 1 molar solution of Fe(NO₃) ₂.

Refer to Exhibit 17-1. Which of the following is the chemical equation for the cell reaction that is spontaneous as written?

• A) 3Fe(NO₃)₂(aq) + 2Al(NO₃)₃(aq) + 6e^- → 2Al(s) + 3Fe(s) + 5NO₃^-(aq)
• B) 3Fe(s) + 2Al³⁺ → 2Al(s) + 3Fe²⁺
• C) Fe(s) + Al³⁺ → Al(s) + Fe³⁺
• D) Al(s) + 2Fe³⁺ → 2Fe(s) + 3Al³⁺ (aq)
• E) None of the above
