Consider the half-reaction below with an E° value of –2.069 V:

[AlF₆]^3–(aq) + 3 e^– → Al(s) + 6 F^–(aq)

Determine the formation constant (K_f) of [AlF₆]^3–. [Use E°_red Al³⁺ = –1.662 V]

Identify whether the following statement is True or False: The value of ΔG° will be positive and K will be less than 1 when a reaction has a positive E° value.

Predict the sign of E° when K > 1 and determine the value of K if E° = 0 V.

Consider the reaction of Cu²⁺(aq) and Ni(s) at 25 °C. Calculate the equilibrium constant for this reaction using reduction potentials.
