[SOLVED] Nernst Equation Applied to Half-Reactions
The Nernst equation can be applied to half-reactions.
Calculate the reduction potential (at 25°C) of the half-cell
Cu/Cu2+ (1.9×10-4 M).
(The half-reaction is Cu2+ + 2e- --> Cu. E° = 0.34 V)
0.34-[ (8.314)(298)/ (2)(96485)] * ln(1.9E-4)
This produces an answer of 0.45 V which I am confident is
the correct answer to this question but it says incorrect.
Am I approaching this question wrong, or doing the
calculations wrong?
