Electrolytic Cell Nonspontaneous Electrical energy chemical energy E = - = + Anode= Cathode= ΔG Ex: electrolysis oxidation reduction As reaction progresses, K doesn’t When rxn is shifting When rxn is shifting left When a reaction is at change BUT right equilibrium Q approaches K Q < K Q > K Q = K - G approaches 0 G = + G = 0 G = E approaches 0 E = + E = - E = 0
