Cell Potential Under Non-standard Conditions Practice Test

For the following cell reaction:

2 Al (s) + 3 Mn2+ (aq) -> 2 Al3+ (aq) + 3 Mn (s)

predict if the cell potential Ecell will be larger, or smaller than Eocell for the following conditions: <u>Al3+</u> = 1.0 M; <u>Mn2+</u> = 5.0 M.

What is the cell potential of the following cell:

Zn (s) + 2 H+(aq) -> Zn2+ (aq) + H2 (g) Eo = 0.76 V

When the <u>Zn2+</u> = 1.0 M; PH2 = 1 atm, and the pH in the cathode is 5.2?
