Zn²⁺(aq)+ 2 Fe²⁺(aq)

question 63

Multiple Choice

Calculate the cell potential,at 25 ^$\circ$ C,based upon the overall reaction
Zn²⁺(aq) + 2 Fe²⁺(aq) $\to$ Zn(s) + 2 Fe³⁺(aq)
If [Zn²⁺] = 1.50 $\times$ 10^-4 M,[Fe³⁺] = 0.0200 M,and [Fe²⁺] = 0.0100 M.The standard reduction potentials are as follows:
Zn²⁺(aq) + 2 e^- $\to$ Zn(s) $~~~~~~~~$ E ^$\circ$ = -0.763 V
Fe³⁺(aq) + e^- $\to$ Fe²⁺(aq) $~~~~~~~~$ E ^$\circ$ = +0.771 V

• A) -1.665 V
• B) -1.534 V
• C) -1.439 V
• D) -0.008 V
• E) +0.008 V
