Which of the following is the reaction half- reaction for a storage battery ?

Answer»

`PbO_(2 (s))+ SO_(4)^(2-) + 4 H^(+) + 2e^(-)to PbSO_(4 (s)) + 2 H_(2)O`
`Pb_((s)) + PbO_(2 (s)) + 2 H_(2)SO_(4) to 2 PB SO_(4 (s)) + 2 H_(2)O`
`Pb_((s)) + H_(2)SO_(4) to PbSO_(4 (s)) + 2 H^(+) + 2e^(-)`
`2 PbSO_(4 (s)) + 2 H_(2)O to Pb_((s)) + PbO_(2(s)) + 2 H_(2)SO_(4)`

Solution :Reduction half- cell reaction .
`PbO_(2 (S))+ 4H^(+) + SO_(4)^(2-) +2 E^(-) to PbSO_(4 (S)) + 2 H_(2)O`
OXIDATION half -cell reaction .
`Pb_((S)) + SO_(4)^(2-) + 2 e^(-)`
