Question

Part B:

Calculate the formation constant for the formation of [Cu(NH3)4(H2O)2]2+ from [Cu(H2O)6]2+, given that ΔG∘ is −74.2kJ⋅mol−1 at 298 K.

Express your answer numerically to three significant figures.

Part C:

Consider the formation of [Ni(en)3]2+ from [Ni(H2O)6]2+. The stepwise ΔG∘ values at 298 Kare

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−1Calculate the overall formation constant (Kf) for the complex [Ni(en)3]2+.

Express your answer numerically to three significant figures.
