Calculate the Cell Potential,at 25 \circ C,based Upon the Overall Reaction
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
