A voltaic cell consists of a Ag/Ag⁺ electrode (E° = 0.80 V) and a Fe²⁺/Fe³⁺ electrode (E° = 0.77 V) with the following initial molar concentrations: [Fe²⁺] = 0.30 M; [Fe³⁺] = 0.10 M; [Ag⁺] = 0.30 M. What is the equilibrium concentration of Fe³⁺? (Assume the anode and cathode solutions are of equal volume, and a temperature of 25°C.)

A) 0.030 M
B) 0.043 M
C) 0.085 M
D) 0.11 M
E) 0.17 M
