    (See attached file for full problem description)

    1. The standard-state cell potential for the following reaction is 1.66 V.

    2 Al (s) + 6 H3O+ (aq) --> Al3+ (aq) + 3 H2 (g) + 3 H2O (l)

    Using the information in Table 1, calculate the standard-state half-cell potential for the following half-reaction:

    Al (s) --> Al3+ (aq) + 3 e-

    2. Using the information in Table 1, and the half-cell potential you calculated in Question 1,
    calculate the standard-state cell potential for the following reaction:

    Al (s) + Ag+ (aq) --> Al3+ (aq) + Ag (s)
