write the half-reaction and standard potential of the right half-cell electrode for each of the galvanic cells shown below: Pt | H2,2H + // Pb2 + | Pb E = -0,13V Pt | H2,2H + // Fe3 +, Fe2 + E = 0,77V b) The standard potential of the electrode Zn2 + | Zn is -76V. The standard potential for the galvanic cell Zn | Zn2 + // Sn2 + | Sn is 0.62V. Write the half-reactions that occur at each electrode when this galvanic cell produces current. What is the standard electrode potential? of the electrode Sn2 + | Sn?
