the electroplating of a silver spoon, the spoon acts as thecathode and a piece of pure silver as the anode. Both dipinto a solution of silver cyanide (AgCN). Suppose that acurrent of 1.5 A is passed through such a cell for 22 minutesand that the spoon has a surface area of 16cm2. Calculatethe average thickness of the silver layer deposited onthe spoon, taking the density of silver to be 10.5gcm3.

Determine the overall reaction and its standard cell potential at 25 C for the reaction involving the galvanic cell made from a half-cell consisting of a silver electrode in 1 M silver nitrate solution and a half-cell consisting of a zinc electrode in 1 M zinc nitrate. Is the reaction spontaneous at standard conditions?

a Calculate G for the following cell reaction: Tl(s)Tl+(aq)Pb2+(aq)Pb(s) The Gf for Tl+(aq) is 32.4 kJ/mol. b From G, calculate the standard cell potential for the cell reaction and from this, determine the standard potential for Tl2+(aq)+eTl(s).

Determine the overall reaction and its standard cell potential at 25 C for the reaction involving the galvanic cell in which cadmium metal is oxidized to 1 M cadmium(II) ion and a half—cell consisting of an aluminum electrode in 1 M aluminum nitrate solution. 15 the reaction spontaneous at standard conditions?
