question 76

Multiple Choice

Which of the following is the balanced overall reaction and standard cell potential of an electrochemical cell constructed from half-cells with the given half reactions?
Pt²⁺(aq) + 2 e- ? Pt(s) ; E° = 1.180 V
Pb²⁺(aq) + 2 e- ? Pb(s) ; E° = -0.130 V

• A) Pt²⁺(aq) + Pb(s)? Pt(s) + Pb²⁺(aq); \(E _ { \text {cell } } ^ { \circ }\) = 1.310 V
• B) Pt(s) + Pb²⁺(aq) ? Pt²⁺(aq) + Pb(s); \(E _ { \text {cell } } ^ { \circ }\) = ?1.310 V
• C) Pt²⁺(aq) + Pb²⁺(aq) ? Pt(s) + Pb(s); \(E _ { \text {cell } } ^ { \circ }\) = 1.050 V
• D) Pt²⁺(aq) + Pb(s) ? Pt(s) + Pb²⁺(aq); \(E _ { \text {cell } } ^ { \circ }\) =0.655 V
• E) Pt(s) + Pb²⁺(aq) ? Pt²⁺(aq) + Pb(s); \(E _ { \text {cell } } ^ { \circ }\) = ?0.655 V
