Nernst Equation - Relation To Equilibrium

Relation To Equilibrium

At equilibrium, E = 0 and Q = K. Therefore

\begin{align} 0 &= E^o - \frac{RT}{nF} \ln K\\ \ln K &= \frac{nFE^o}{RT} \end{align}

Or at standard temperature,

We have thus related the standard electrode potential and the equilibrium constant of a redox reaction.

Famous quotes containing the words relation to, relation and/or equilibrium:

    “Any relation to the land, the habit of tilling it, or mining it, or even hunting on it, generates the feeling of patriotism. He who keeps shop on it, or he who merely uses it as a support to his desk and ledger, or to his manufactory, values it less.”
    —Ralph Waldo Emerson (1803–1882)

    “Parents ought, through their own behavior and the values by which they live, to provide direction for their children. But they need to rid themselves of the idea that there are surefire methods which, when well applied, will produce certain predictable results. Whatever we do with and for our children ought to flow from our understanding of and our feelings for the particular situation and the relation we wish to exist between us and our child.”
    —Bruno Bettelheim (20th century)

    “When a person hasn’t in him that which is higher and stronger than all external influences, it is enough for him to catch a good cold in order to lose his equilibrium and begin to see an owl in every bird, to hear a dog’s bark in every sound.”
    —Anton Pavlovich Chekhov (1860–1904)
