← ScienceWhich consequence results when an aluminum electrolysis cell experiences electrolyte depletion?
A)Increased overpotential for aluminum reduction
B)Decreased anode carbon dioxide production
C)Equilibrium shift favoring alumina formation✓
D)Enhanced cryolite dissolution kinetics
💡 Explanation
Alumina depletion reduces its concentration; therefore, equilibrium shifts toward alumina formation to restore equilibrium, rather than favoring aluminum reduction; The Le Chatelier's principle defines this mechanism; it would happen under reactant-starved state because otherwise less reactants form.
