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)

In a galvanic cell, a spontaneous redox reaction occurs. However the reactants are separated such that the transfer of electrons is forced to occur across a wire. The resulting electricity is measured in volts (V) and is the sum of the potentials of the oxidation and reduction half-reactions: E^o cell = E^o red + E^o ox By reversing the reduction half-reactions, you get the corresponding oxidation half-reaction, for which E^o ox has the opposite sign of E^o red You can...

Chem 1212 Lab Report on electrochemistry
Electrochemistry When electrons transfer between reaction components in a redox reaction, we can harness the motion of the electrons to create a potential. Electrochemistry revolves around the separation of the two half-reactions in a redox reaction and establishing two different electrodes. This might involve physically separating the half-reactions or including a separator, such as a semi-permeable membrane or plastic dividers. With the reactions separated, the electrons will need to flow through the wire connecting...
