A galvanic cell consists of a Cu(s)|Cu2+(aq) half-cell and a Zn(s)|Zn2+(aq) half-cell, connected by a salt bridge. Oxidation occurs in the zinc half-cell. The cell can be represented in standard notation as:

The electrode for which the standard reduction potential of 0.00 V is assigned uses the half-reaction:

A galvanic cell is composed of these two half-cells, with the standard reduction potentials shown: Fe2+(aq) + 2e- Fe(s)-0.44VAl3+(aq) + 3e- Al(s)-1.66VWhat is the standard free energy (ΔG°) change for the cell reaction of this galvanic cell?

Using these metal ion/metal standard reduction potentials:Fe2+(aq)|Fe(s)Zn2+(aq)|Zn(s)Cr3+(aq)|Cr(s)Cu2+(aq)/Cu(s)-0.44 V-0.76 V-0.74 V+0.34 V Calculate the standard cell potential for the cell whose reaction is: Fe2+(aq) + Cr(s) → Fe(s) + Cr3+(aq)
