A concentration cell contains 0.5M aqueous Ag+ on one side and 0.1M aqueous Ag+ on the other. All of the following are true EXCEPT:
A. Electrons will move from the less concentrated side to the more concentrated side
B. Electrons will move from the anode to the cathode
C. As the cell potential moves toward zero, the concentrations of both sides will tend to even out
D. Delta G > 0
ok so the answer is D, but their explanation in the back is "a concentration cell is a type of galvanic cell, it is always spontaneous." i thought that delta G would have to be less than 0 in order for the reaction to be spontaneous, and in the text it seems like that is the case for galvanic cells. am i missing something? or is this an error?
