An electrochemical cell is constructed by dipping a zinc rod in a solution of Zn(NO3)2(aq), dipping a cobalt rod in a solution of CoCl2(aq), and connecting them with a wire and a salt bridge. In the cell that is constructed, the metallic zinc is being oxidized. a. Write cell line notation for the electrochemical cell. No include spectator ions. b. Doubling the mass of the zinc electrode from 5 g to 10 g will cause the measured voltage of the cell to, select one... (decrease, stay the same, increase,need more information) c. Increasing the concentration of zinc ions, Zn2+ , in solution will cause the measured voltage of the cell to, select one... (decrease, stay the same, increase,need more information) d. The standard cell potential for this electrochemical cell is 0.482 V and two moles of electrons are exchanged per mole of reaction. What is equilibrium constant, ?, for the redox reaction described by this electrochemical cell at 298 K?
