consider the cell Ag I Ag+ (aq. 5.0 mmol.L^-1)II Ag+ (aq 0.15 mol.L^-1)I Ag. can this cell do work? if so, what is the maximum work that it can perform (per mole of Ag)?

This is an example of a problem using a concentration cell. The overall reaction for a concentration cell is Ag+ (0.15M) -> Ag+ (0.005 M) because the reaction will always proceed from the higher concentration to the lower concentration. Then, using the Nernst Equation, you can determine what Ecell of the reaction is. Once you calculate Ecell, you can calculate delta G, which is equal to -nFE. Once you calculate delta G, you know maximum work, because delta G is equal to maximum work.
