Electrode and Cell Potentials

In a circuit, the flow of charge is a result of an

electrical potential difference between two points in the circuit.

electrochemical reaction

The driving force of a(n) ________ is measured by the standard cell potential.

Electrical potential

the ability of the electric field to do work on the charge

Cell potential

electrical potential difference in a galvanic cell

E°cell = E°cathode

E°anode

E°cell =

E°cathode - E°anode

Standard potentials (E°) are measured with

All aqueous concentrations at 1M

The pressure of all gases at 1 atm

Temperature held constant (usually at 25 °C)

Units of E° is V or mV

The driving force of an electrochemical reaction is measured by

the standard cell potential.
