The entropy change of a cell reaction can be determined from the change of the cell potential
Question:
The entropy change of a cell reaction can be determined from the change of the cell potential with temperature.
(a) Show that ΔS° = nF(Ecell,2° – Ecell,1°)/(T2 – T1). Assume that ΔS° and ΔH° are constant over the temperature range considered.
(b) Calculate ΔS° and ΔH° for the cell reaction Hg2Cl2(s) + H2(g) → 2 Hg(l) + 2 H+(aq) + 2 Cl–(aq), given that E° = +0.2699 V at 293 K and +0.2669 V at 303 K.
