Given the Following Two Half-Reactions,write the Overall Reaction in the Direction

question 84

Multiple Choice

Given the following two half-reactions,write the overall reaction in the direction in which it is product-favored,and calculate the standard cell potential. Pb²⁺(aq) + 2 e^- → Pb(s)
E° = -0.126 V
Fe³⁺(aq) + e^- → Fe²⁺(s)
E° = +0.771 V

• A) Pb²⁺(aq)+ 2 Fe²⁺(s)→ Pb(s)+ 2 Fe³⁺(aq); = +0.897 V
• B) Pb²⁺(aq)+ Fe²⁺(s)→ Pb(s)+ Fe³⁺(aq); = +0.645 V
• C) Pb(s)+ 2 Fe³⁺(aq)→ Pb²⁺(aq)+ 2 Fe²⁺(s); = +1.416 V
• D) Pb(s)+ 2 Fe³⁺(aq)→ Pb²⁺(aq)+ 2 Fe²⁺(s); = +0.897 V
• E) Pb(s)+ Fe³⁺(aq)→ Pb²⁺(aq)+ Fe²⁺(s); = +0.645 V
