Question:

Given the following standard potentials in basic solution

and assuming that a reversible reaction can be established on a suitable catalyst, calculate E^⦵, Δ_rG^⦵, and K for the reductions of

(a) CrO₄²⁻

(b) [Cu(NH₃)₂]⁺ in basic solution. Comment on why Δ_rG^⦵ and K are so different between the two cases despite the values of E^⦵ being so similar.
