If the same materials are used to build a voltaic cell and an electrolytic cell, how would the chemical reactions compare?
ОО
The same overall reaction would happen in each cell, but it would take place spontaneously in the voltaic cell.
The same overall reaction would happen in each cell, but it would take place nonspontaneously in the voltaic cell.
The reaction in the voltaic cell would be nonspontaneous and the reverse of the reaction in the electrolytic cell.
The reaction in the voltaic cell would be spontaneous and the reverse of the reaction in the electrolytic cell.
