Use the standard half-cell potentials listed below to calculate the standard cell potential for the following reaction occurring in an electrochemical cell at 25°C. (The equation is balanced.) Pb(s) + Br2(l) → Pb2+(aq) + 2 Br⁻(aq)Pb2+(aq) + 2 e⁻ → Pb(s) E° = -0.13 VBr2(l) + 2 e⁻ → 2 Br⁻(aq) E° = +1.07 V
