- 4. Consider an electrochemical cell at 25°C with the overall reaction as below. Fe2+ + Ag, Fet + Ag, Given that [Fe²+] = [Fe3+] = 0.0050 M and [Ag+] = 2.0 M. a) Write the oxidation and reduction half-reactions. b) Calculate the standard emf (E cel of the electrochemical cell. c) Calculate the standard free-energy change (Gº). d) Calculate the emf (Ecel)of the electrochemical cell. e) Calculate the[Fe2] where the cell reaction reaches equilibrium. f) If the cell is operated as an electrolytic cell using a current of 0.5 A to force the electrons to flow in the reverse direction (nonspontaneous reaction) for 1.5 h, calculate the increment of Ag amount (in mol unit).
