Consider the following self-exchange electron transfer reactions (* indicates a radioactive isotope): 1. [Fe(H2O)6]2+ + [Fe*(H2O)6]3+ → [Fe(H2O)6]3+ + [Fe*(H2O)6]2+ (Rate constant: k11)2. [Fe(bpy)3]2+ + [Fe*(bpy)3]3+ → [Fe(bpy)3]3+ + [Fe*(bpy)3]2+ (Rate constant: k22)3. [Co(NH3)6]2+ + [Co*(NH3)6]3+ → [Co(NH3)6]3+ + [Co*(NH3)6]2+ (Rate constant: k33) The rate constants in these reactions at a certain temperature follow the order:
