Problem

At 298 K a galvanic cell employs the half-reactions below. Ag⁺ + e⁻ → Ag(s)  E° = +0.80 V Fe³⁺ + e⁻ → Fe²⁺  E° = +0.77 V With [Fe³⁺] = 0.010 M and [Fe²⁺] = 0.10 M, the cell potential is measured to be 0.10 V. What is the concentration of Ag⁺ in the Ag⁺/Ag half-cell? (a) 6.6×10−3 M6.6\times10^{-3}\ \text{M} (b) 1.5 M1.5\ \text{M} (c) 15 M15\ \text{M} (d) 0.15 M0.15\ \text{M}
