AP CHEMISTRYGalvanic vs Electrolytic Cells
Compare galvanic cells (spontaneous, ΔG < 0, generate electricity) with electrolytic cells (non-spontaneous, ΔG > 0, require external voltage). Visualize how galvanic cells convert chemical energy to electrical energy in batteries, while electrolytic cells use electrical energy to drive non-spontaneous reactions in electroplating, electrolysis, and metal purification. Understand electrode polarity differences and the role of external power sources.
