NERNST EQUATION Meaning and Definition

  1. The Nernst equation is a mathematical equation that relates the concentration of a species in a solution to the voltage or potential difference across an electrochemical cell. It is named after Walther Nernst, a German chemist and physicist who formulated this equation in 1889.

    The Nernst equation is commonly used in the field of electrochemistry to determine the electrode potential of an electrochemical reaction at a given concentration, temperature, and pressure. It provides a quantitative relationship between the cell potential, the standard cell potential, the gas constant, the temperature, and the activity or concentration of the species involved in the reaction.

    In its simplest form, the Nernst equation is expressed as:

    E = E° - (RT/nF) * ln(Q)

    Where:

    - E is the cell potential

    - E° is the standard cell potential

    - R is the gas constant

    - T is the temperature in kelvin

    - n is the number of moles of electrons transferred in the redox reaction

    - F is Faraday's constant

    - Q is the reaction quotient, which is the ratio of concentrations of products to reactants, each raised to their stoichiometric coefficients.

    The Nernst equation is essential for understanding various electrochemical processes, including electroplating, corrosion, and energy conversion in fuel cells. It allows scientists and engineers to determine the feasibility of an electrochemical reaction and predict how changing parameters such as concentration or temperature will affect the cell potential.
