The overall reaction in the lead storage battery is below.

Pb(s) + PbO2(s) + 2 H+(aq) + 2 HSO4-(aq) 2 PbSO4(s) + 2 H2O(l)

(a) Calculate at 25°C for this battery when [H2SO4] = 3.8 M; that is, [H+] = [HSO4-] = 3.8 M. At 25°C, ° = 2.04 V for the lead storage battery.

V

(b) For the cell reaction ΔH° = -315.9 kJ and ΔS° = 263.5 J/K. Calculate ° at -20°C.

V

(c) Calculate at -20°C when [H2SO4] = 3.8 M.
