What is Meant by the Nernst Equation?

In Chemistry, the Nernst equation is an equation which relates the Gibbs free energy and the cell potential. To calculate the cell potential, Nernst equation takes the value of temperature, standard electrode potential, activity and the reaction quotient. This equation is used to determine the single electrode reduction and oxidation potential under any conditions.
