How does the Nernst Equation work?

E = E° − (0.0592/n) × log(Q) at 25°C Then: n = moles of electrons transferred Then: Q = reaction quotient (product of concentrations) Then: E > 0 means cell is spontaneous; E = 0 means equilibrium.

Can you give an example of how to use the Nernst Equation?

Example: Input E°=1.10V (Zn-Cu cell) · n=2 · Q=0.001 gives a result of E = 1.10 − (0.0592/2)×log(0.001) = 1.10+0.089 = 1.189V (Dilute reactant → higher cell potential).

The Nernst equation calculates the electrode potential of an electrochemical cell under non-standard conditions (non-unit concentrations). E = E° − (RT/nF) × ln(Q). At 25°C it simplifies to E = E° − (0.0592/n) × log(Q).

Did You Know?

The Nernst equation explains why a battery's voltage drops as it discharges — as reactants are consumed, Q increases, reducing E until E=0 at full discharge.
