3: Construct a galvanic cell, write the cell notation, calculate the cell potential, free energy, and equilibrium constant. (Refer to the standard reduction potential table to find out the stronger reducing agent.)

a: A galvanic cell consists of one half-cell with Fe dipping into an aqueous solution of 1.0 M FeCl₂ and the other half-cell with Ag dipping into an aqueous solution of 1.0 M AgNO₃.
