Concentration cell EMF (Ecell = (0.0591/n) log (c_conc/c_dil) for same electrode pair)
jee-mainjee-advancedneet-ug
Ecell = (0.0591/n) log (c_conc/c_dil) for same electrode pair
What each symbol means
| Symbol | What it stands for |
|---|---|
| c_{\mathrm{dil}} | Lower [M⁺] compartment (anode / dissolution side) |
| c_{\mathrm{conc}} | Higher [M⁺] compartment (cathode / reduction side for a spontaneous metal concentration cell) |
When to use this
Same metal electrodes; only [M⁺] differs; 298 K; n for Mⁿ⁺ + ne⁻ → M; cathode is the higher-concentration half-cell.
