Question

Quizplus · Accepted Answer

The addition of 5.0 M AgNO3 to the compartment containing the 1.0 M Ag⁺(aq) will increase the concentration of Ag+ ions, which will shift the equilibrium of the half-reaction: Ag+ + e- ⇌ Ag to the left, decreasing the concentration of Ag+ ions in solution. This shift will drive the overall cell reaction to proceed in the direction favored by the reduction potential of the Cu2+/Cu half-reaction, resulting in an increase in cell voltage. Therefore, the cell voltage will increase.

The Initial Concentrations of Ag+(aq)and Cu2+(aq)are Both 1
