Problem

\mathrm{Ag^+ + e^- \to Ag}

, with

z=1

electron transferred. As the bath is used, the silver-ion concentration falls by a factor of

100

. Treating the activity of

\mathrm{Ag^+}

as proportional to its concentration, and taking the bath temperature as

298\,\mathrm{K}

, find the shift in the electrode potential caused by this depletion.
