please answer #5 type the answer or write it clearly so i can understand please
1. Using data in Table 1 (see next page), calculate the standard emf for a cell that employs
the following overall cell reaction:
2AI(s) + 31(s)
→ 2 Al3+ (ag) + 6I° (ag)
2. Using Table 1, rank the following species from the strongest to the weakest reducing
agent: I (ag), Fe(s), Al(s). Explain why.
3. Using the standard reduction potentials in Table 2, calculate the equilibrium constant at
25°C for the reaction
Br2(1) + 2C1(ag)
Cl2(g) + 2 Br(aq)
4. Based on the standard reduction potentials in Table 2, which of the following metals could
provide çathodic protection to iron: Al, Cu, Ni, Zn?
5. The electrolysis of CuCI(ag) produces Cu(s) and Cl2(g). What is the minimum external emf
needed to drive this electrolysis under standard conditions?
