Concentration Effects on Cell Potential
In a galvanic cell composed of a zinc electrode in a 1.0 M ZnSO₄ solution and a copper electrode in a 1.0 M CuSO₄ solution, the concentration of Cu²⁺(aq) is increased to 2.0 M. Which statement correctly describes the effect on the cell potential and provides the reason for this change?
A
Cell potential decreases; system not at equilibrium
B
Cell potential remains unchanged; system at equilibrium
C
Cell potential increases; system not at equilibrium
D
Cell potential decreases; Le Châtelier’s principle applies
