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? Mn 2+(aq) + 2 e−→Mn(s); E° = –1.180 V Pb2+(aq) + 2 e−→ Pb(s); E° = –0.130 V Group of answer choices Pb 2+(aq) + Mn(s) →Pb(s) + Mn2+(aq); = 1.050 V Pb(s) + Mn2+(aq) →Pb2+(aq) + Mn(s); = −1.050 V Pb 2+(aq) + Mn2+(aq) →Pb(s) + Mn(s); = –1.310 V Pb 2+(aq) + Mn(s) →Pb(s) + Mn2+(aq); =0.525 V Pb(s) + Mn2+(aq) →Pb2+(aq) + Mn(s); = −0.525 V
