Electrochemistry Electrochemistry deals with the relationship between chemical change and electricity lectrochemical cells (two types) Electrochemical cells (two types) Voltaic (Galvanic) cells – use a spontaneous ( G < 0) reaction to roduce electricity (batteries) produce electricity (batteries) Electrolytic cells – use a source of electricity to drive a non- spontaneous ( G > 0) reaction lectrolysis) 21-2 (electrolysis)
