Thermodynamics and Electrochemistry Glossary

Electrode where oxidation occurs.

Electrode where reduction occurs.

Cell using external electricity to drive a non-spontaneous reaction.

Thermodynamic quantity measuring energy dispersal; units J/(mol K).

96485 C/mol; charge of one mole of electrons.

Cell producing electricity from a spontaneous redox reaction.

G = H - TS; criterion for spontaneity at constant T and P.

E = E0 - (RT/nF)lnQ; relates cell potential to non-standard conditions.

Connection allowing ion flow between half-cells to maintain electrical neutrality.

Process that occurs without continuous external input; delta-G < 0.

Voltage of an electrochemical cell under standard conditions (1M, 1atm, 25C).

Voltage for a half-reaction written as reduction, relative to SHE.
