The Nernst equation is one of the most important equations in
electrochemistry. To calculate the cell potential at non-standard-state
conditions, the equation is
E = E°.
2.303 RT log10
nF
where E is the potential in volts, Eº is the standard potential in volts,
R is the gas constant, T is the temperature in kelvins, n is the number
of moles of electrons transferred, F is the Faraday constant, and Qis
the reaction quotient. Using the common reference temperature, 25
°C or 298 K, the equation has the form
Q=
E = Eº - (0.0592
The reaction quotient has the usual form
⁹2) log Q
[products]
[reactants]"
A table of standard reduction potentials gives the voltage at standard
conditions, 1.00 M for all solutions and 1.00 atm for all gases. The
Nernst equation allows for the calculation of the cell potential E at
other conditions of concentration and pressure.
