What is the standard cell potential (E°cell) in volts for a redox reaction where one electron is transferred and the equilibrium constant (K) is 7.23 × 10^8?

Calculate the standard cell potential for the electrochemical cell: Pb2+(aq) + Mn(s) → Pb(s) + Mn2+(aq). Given the standard reduction potentials: E°(Pb2+/Pb) = -0.13 V and E°(Mn2+/Mn) = -1.18 V.
