A Concentration Cell Is Constructed by Using the Same Half-Reaction

A concentration cell is constructed by using the same half-reaction for both the cathode and anode. What is the value of E_cell for a concentration cell that combines silver electrodes in contact with 0.10 M silver nitrate and 0.00003 M silver nitrate solutions? ( = +0.80 V for Ag/Ag⁺)

A) (+0.21 V)
B) (+0.59 V)
C) (+0.80 V)
D) (-0.21 V)
E) (+1.01 V)
