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)
Given the standard reduction potentials:
Pb2+(aq) + 2 e- → Pb(s) E° = -0.13 V
Br2(l) + 2 e- → 2 Br-(aq) E° = +1.07 V
What is the standard cell potential (E°cell) for the reaction?
