2. a. Calculate the electromotive force, or emf (E) for the following concentration cell at 25°C: Cu(s) | Cu* (aq, 0.080 M) | (KCI, sat'd) | Cu* (aq, 1.2 M) | Cu(s) (E° (Cu"/Cu): 0.34 V; R: 8.314 J/mol. K; 1F= 96500 J/V.mol) b. Is it possible to obtain energy with such concentration cell? Make a comment on this based on your result in a. c. When does E become zero? Show the conditions. 2. a.
