Answer to Question #77585 in Physical Chemistry for Jamie

Question

Consider the following standard electrode potentials

Ag+ + e- = Ag, Eo = 0.80 V

Mn2+ + 2e- = Mn, Eo = -1.18 V


for the standard cell

Mn|Mn2+(aq)||Ag+(aq)|Ag


Which of the following statements are true?

1. The cell voltage will be 1.98 V.

2. One half-cell reaction is Mn = Mn2+ + 2e-
.

3. The overall cell potential will decrease with
time.
