General Chemistry 2
Summary
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, the anode undergoes oxidation and the cathode undergoes reduction, 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, necessitating an external power source.
- The charges on the anodes and cathodes are opposite in the two types of cells, affecting the direction and necessity of electron flow.
