Cоnsider аn electrоchemicаl cell invоlving the overаll reaction 2 AgBr(s) + Pb(s) → Pb2+(aq) + 2 Ag(s) + 2 Br–(aq) Each half-reaction is carried out in a separate compartment. The anion included in the lead half-cell is NO3–. The cation in the silver half-cell is K+. The two half-cells are connected by a KNO3 salt bridge. If [Pb2+] = 1.0 M and [Br-] = 0.14 M, what is the E° of the cell at 298 K?Given: AgBr(s) + e– → Ag(s) + Br–(aq) E° = +0.07 V. Pb+2 + 2e– → Pb(s) E° = - 0.13 V.
