What is electrochemical potential?

Electrochemical Potential

In electrochemistry, the electrochemical potential, sometimes abbreviated to ECP, is a thermodynamic measure that combines the concepts of energy stored in the form of chemical potential and electrostatics. Electrochemical potential is expressed in the unit of J/mol.

Famous quotes containing the word potential:

    If the Russians have gone too far in subjecting the child and his peer group to conformity to a single set of values imposed by the adult society, perhaps we have reached the point of diminishing returns in allowing excessive autonomy and in failing to utilize the constructive potential of the peer group in developing social responsibility and consideration for others.
    Urie Bronfenbrenner (b. 1917)
