question 41

Multiple Choice

A voltaic cell prepared using zinc and iodine has the following cell notation.
Zn(s) | Zn²⁺(aq) || I^-(aq) | I₂(s) | C(graphite)
Which of the following equations correctly represents the balanced, spontaneous, cell reaction?

• A) 2I^-(aq) + Zn²⁺(aq)  I₂(s) + Zn(s)
• B) I₂(s) + Zn(s)  2I^-(aq) + Zn²⁺(aq)
• C) 2I^-(aq) + Zn(s)  I₂(s) + Zn²⁺(aq)
• D) I₂(s) + Zn²⁺(aq)  2I^-(aq) + Zn(s)
• E) None of the above, since graphite must be in the equation.
