The galvanic cell Zn (s) ¦ Zn2+(aq) ¦¦ Ni2+(aq) ¦ Ni (s) is constructed using a zinc electrode that weighs 32.68 g and is completely immersed in 325 mL of 1.00 M ZnCl2 (aq) and a nickel electrode that weighs 41.33 g and is immersed in 575 mL of 1.00 M NiCl2 (aq) solution. A steady current of 0.0715 A is drawn from the cell as the electrons move from the zinc electrode to the nickel electrode.
(a) Calculate E for the cell and the equilibrium constant for the overall reaction.
(b) Which reactant is limiting in this cell?
(c) How long will it take for the cell to be completely discharged?
(d) How much will each of the electrodes weigh when the cell is completely discharged?
