Nernst Equation
It relates electrode potential with the concentration of ions. Thus, the reduction potential increases with the increase in the concentration of ions. For a general electrochemical reaction of the type.
Nernst equation can be given as
Substituting the values of R and F we get
Application of Nernst Equation
Equilibrium Constant from Nernst Equation:
For a Daniel cell, at equilibrium
But at equilibrium,
In general,
