question 35

Multiple Choice

A lead storage battery involves the following two half-reactions:
PbSO₄(s) + 2e^- → Pb(s) + SO₄^2-(aq) ; E° = -0.36 V
PbO₂(s) + 4H⁺(aq) + SO₄^2-(aq) + 2e^- → PbSO₄(s) + 2H₂O(l) ; E° = 1.69 V
During the discharge reaction of the lead storage battery at 1.0 M concentrations,the cell potential and the reducing agent are,respectively,

• A)2.05 V and PbO₂.
• B)-2.05 V and PbO₂.
• C)1.33 V and Pb.
• D)-2.05 V and Pb.
• E)2.05 V and Pb.
