Part A: Calculate the formation constant for the formation of [Cu(en)(H2O)4]2+ from [Cu(H2O)6]2+, given that ΔG° is -60.1kJ⋅mol-1 at 298 K.
Part B: Consider the formation of [Ni(en)3]2+ from [Ni(H2O)6]2+. The stepwise ΔG° values at 298 K are
ΔG°1 for first step=-42.9 kJ⋅mol-1
ΔG°2 for second step=-35.8 kJ⋅mol-1
ΔG°3 for third step=-24.3 kJ⋅mol-1
Calculate the overall formation constant (Kf) for the complex [Ni(en)3]2+.
