How does the Nernst equation modify E° under nonstandard conditions?
A.E = E° − (0.0592/n) log Q at 25 °C
B.E = E° + (0.0592/n) log Q
C.E = E° always
D.E = nFE°
Explanation
Core Concept
The Nernst equation corrects the potential for concentrations away from 1 M. At equilibrium Q = K and E = 0.
Correct Answer
AE = E° − (0.0592/n) log Q at 25 °C
