Labelling a Galvanic Cell

Pb(s)| Pb2+ (1M) || Ag+ (1M) | Ag(s)
Determine which of the following statements about the cell shown are True or False.

The silver half-cell is the anode.
The mass of the silver electrode is increasing.
Electrons are spontaneously produced in the lead half-cell.
As the reaction proceeds, the concentration of the silver ions decreases.
The standard cell potential, Eo, equals 1.73 V.
Cations move from the lead half-cell to the silver half-cell.
The lead electrode is the anode.
The cell, as represented by the line notation, is an electrolytic cell.

Please see the attached file for the fully formatted problems.

In your cell, the half-reactions are:

Ag+ + 1 e- --> Ag (s) 0.80 V
Pb+2 + 2e- --> Pb (s) -0.13 V

Because the lead reaction is negative, it is more likely to occur in the opposite direction:

Pb (s) --> Pb+2 + 2 e- 0.13 V

The half-reactions will be:

Ag+ + 1 e- --> Ag (s) 0.80 V
Pb (s) --> Pb+2 + 2 e- 0.13 V

Below, your answers are in parentheses and the correct answers are in caps:

The silver half-cell is the anode. ...
