The Nernst equation | Applications of thermodynamics | AP Chemistry | Khan Academy

The Nernst equation relates the instantaneous potential, E, to the standard potential, E°, and the reaction quotient, Q: E = E° - (0.0592 V/n)logQ at 298 K. When all reactants and products are in their standard states, Q = 1 and E = E°. When the reaction is at equilibrium, Q = K and E = 0.
