Because of environmental reasons, lead acid batteries will be
converted to NickelCadmium (NI-CD) Batteries. Calculate theoretical
efficiency change for the assuming all cells have same molar
concentrations.
A lead-acid battery uses a redox reaction in which lead(0) and
lead(IV) are both converted to lead(II). This reaction is
facilitated by the presence of sulfuric acid, H2SO4, as shown by
the reaction
Pb+PbO2+2H2SO4→2PbSO4+2H2O
Suppose that a fully charged lead-acid battery contains 1.50 L
of 5.00 M H2SO4. What will be the concentration of H2SO4
in the battery after 3.60 A of current is drawn from the battery
for 6.00 hours ?
