(a) Write the line notation for the following cell.

(b) Calculate the potential of each half-cell and the cell voltage, E. In which direction will electrons flow through the circuit? Write the spontaneous net cell reaction.
(c) The left half-cell was loaded with 14.3 mL of Br2(l)(density = 3.12 g/mL). The aluminum electrode contains 12.0 g of Al. Which element, Br2 or Al, is the limiting reagent? (That is, which reagent will be used up first?)
(d) If the cell is somehow operated under conditions in which it produces a constant voltage of 1.50 V, how much electrical work will have been done when 0.231 mL of Br2(l) has been consumed?
(e) If the potentiometer is replaced by a 1.20 - kΩ resistor and if the heat dissipated by the resistor is 1.00 × 10-4 J/s, at what rate (grams per second) is Al(s) dissolving? (In this question, the voltage is not 1.50 V.)
