Cell Comparison

The content provides a comparative analysis of Galvanic and electrolytic cells, focusing on their operational differences and the nature of electron flow within each.
  • Galvanic cells operate spontaneously with a negative delta G, while electrolytic cells require external energy to proceed due to their positive delta G.
  • In both cell types, oxidation occurs at the anode and reduction at the cathode, with electrons flowing from the anode to the cathode.
  • The major difference lies in the electron flow: it is free in Galvanic cells but forced in electrolytic cells due to the latter's non-spontaneous nature.
  • Another distinction is the charge of the electrodes: in Galvanic cells, the anode is negative and the cathode is positive, whereas in electrolytic cells, these charges are reversed.
