Use the below electrochemical data on ruthenium complexes in acidic media to address the following questions:
[Ru(NH₃)₆]³⁺ + e* → [Ru(NH₃)₆]²⁺ E° = +0.10 V
[Ru(CN)₆]³⁻ + e* → [Ru(CN)₆]⁴⁻ E° = +0.85 V
[Ru(bpy)₃]³⁺ + e- → [Ru(bpy)₃]²⁺ E° = +1.53 V
A. Which of the three ligands best stabilizes the +2 oxidation state over the +3?
B. Calculate AGº for the following reaction:
[Ru(CN)₆]³⁺ + [Ru(bpy)₃]²⁺ → [Ru(CN)₆]⁴⁻ + [Ru(bpy)₃]³⁺
