Answer :

Pb has the oxidation state of +4 in PbO2 and it reduces to PbSO4 where oxidation state is +2. Thus, 2 electrons (+4 - +2) electrons are required for this reduction reaction to take place.

Since 2 electrons are accepted are used up in this reduction process, so by Faraday’s law of electrolysis,

1 mole of Pb requires 2F electricity to carry out the reduction.
