Question 122

Multiple Choice

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 V
Br2(l) + 2 e- → 2 Br-(aq) E° = +1.07 V


A) +1.20 V
B) +0.94 V
C) -0.94 V
D) -1.20 V
E) -0.60 V
