Calculate $E _ { \text {cell } } ^ { \circ }$

question 43

Multiple Choice

Calculate $E _ { \text {cell } } ^ { \circ }$ for the electrochemical cell Pb(s) |PbCl₂(s) | Cl^-(aq, 1.0 M) || Fe³⁺(aq, 1.0 M) , Fe²⁺(aq, 1.0 M) | Pt(s) . The standard reduction potentials are as follows:
Pb²⁺(aq) + 2 e^- ? Pb(s)
E° = -0.126 V
PbCl₂(s) + 2 e^- ? Pb(s) + 2 Cl^-(aq)
E° = -0.267 V
Fe³⁺(aq) + e^- ? Fe²⁺(aq)
E° = +0.771 V
Fe²⁺(aq) + e^- ? Fe(s)
E° = -0.44 V

• A) -0.504 V
• B) -0.062 V
• C) +0.504 V
• D) +1.038 V
• E) +1.604 V
