alleryThe Nernst equation at 25°C for a cell reaction is:
A$E = E° - (0.0591/n) \log Q$
B$E = E° + (0.0591/n) \log Q$
C$E = E° \times (RT/nF) \ln Q$
D$E = E° - n F \log Q$
Answer & Solution
Correct answer: A. $E = E° - (0.0591/n) \log Q$
Nernst equation at 25°C: E = E° − (0.0591/n) log Q (using base-10 log; for natural log, it's E° − (RT/nF) ln Q).
Predicts EMF at non-standard conditions.
