A galvanic cell is composed of these two half-cells, with the standard reduction potentials shown:

Cu2+(aq) + 2 e- ---->Cu(s)
+0.34volt

Cd2+(aq) + 2 e- ---->Cd(s)
-0.40volt
What is the standard free energy change for the cell reaction of this galvanic cell?

  • Chemistry -

    Reverse the Cd half cell and add to the Cu half cell as written. Calculate Eo cell.
    Then dG = -nFEcell.
    n is 2 and F is 96,485.

    It would be more than nice if you didn't switch screen names.
