Hello, Just in need of a little help understanding a spontaneous and non-spontaneous redox reaction spontaneous redox reaction for a battery is Pb(s) +PbO2(s) +SO4(aq) = PbSO4. Does that mean that the non-spontaneous, reverse reaction that occurs and re-charges the battery is PbSO4(s) = Pb(s) + PbO2(S) +SO4(aq)
