Using the Nernst equation to calculate nonstandard cell voltage
A galvanic cell at a temperature of 25.0 °C is powered by the following redox reaction:
3+
3Cu²+ (aq) +2Al(s) → 3 Cu(s)+2A1³* (aq)
2+
Suppose the cell is prepared with 5.29 M Cu
in one half-cell and 2.49 M A1³+ in the other.
Calculate the cell voltage under these conditions. Round your answer to 3 significant digits.
