13. Write the chemical equations for half-cell reactions that occur in the galvanic cell: Mn(s) | Mn²+ (1M) | Fe³+ (1M) | Fe(s) 14. Given the following sets of half-cell reactions write the spontaneous net cell reaction and calculate emf (AE) under standard conditions for the spontaneous changes that will occur: Cr³+ + 3e Cr(s) E°= -0.74V MnO₂ (s) + 4H+ + 2e = Mn²++ 2H₂O Eº= + 1.28V
