What does Nernst equation tell you?


Open in App
Solution

  1. In electrochemistry, the chemical equation that provides the relationship between the standard cell potential, the cell potential of an electrochemical cell, temperature and reaction quotient is called Nernst equation.
  2. So, the Nernst equation is used in the calculation of the cell potential of an electrochemical cell at a particular temperature, pressure, and reactant concentration.
  3. The Nernst equation is,
    E=E0-RTzFlnQ
  4. Here, E is reduction potential, E0 is standard potential, R is the Universal gas constant, T is temperature, z is the number of electrons transferred in the redox reaction, F is Faraday's constant and Q is reaction quotient.
