Please answer it fully and please answer if you're 100% sure of the right answer! 5:33 PM -107 AT&T; 25%, D webassign net (a) Write the line notation for the following cell. (Include states-of-matter under the given conditions in your answer.) (b) Calculate the potential of each half-cell and the cell voltage, E. (Assume that the Nernst potential is 0.05916 V) right half-cell v In which direction will electrons flow through the circuit? O Electrons will flow clockwise through the wire from Pt to Al. O Electrons will flow counterclockwise through the wire from Al to Pt. Write the spontaneous net cell reaction. (Use the lowest possible whole number coefficients. Include states-of-matter under the given conditions in your answer.) (c) The left half-cell was loaded with 13.0 mL of Br2(l) (density 3.12 g/mL). The aluminum electrode contains 11.9 g of Al(s). Which element, Br20) or Al(s), is the limiting reagent? (That is, which reagent will be used up first?) Br20)Explanation / Answer
(a) Cell notation
Al || Al(NO3)2 (0.01 M) || Br2 | HBr (0.1 M) | Pt
(b) For the given electrochemical cell
right half-cell = 1.066 V
Left half-cell = -1.66 V
E = Eo - 0.0592/n logQ
= (1.066 - (-1.66)) - 0.0592/6 log((0.01)^2/(0.1)^3)
= 2.7556 V
Direction of flow of current
Counterclockwise from Al to Pt
Spontaneous net cell reaction,
3Br2(aq) + 2Al(s) ---> 2AlBr3 (s)
(c) With the given reaction condition,
the limiting reagent is,
Br2 (l)
