As reactants are consumed in a working electrochemical cell, the cell potential will also decrease until it reaches zero. The Nernst equation is used to establish the relationship between how cell potential depends on concentration

You can take these two equations that we already know:
and
and combine them to get


when you solve for E, you will get


Since

You can get
(Nernst equation)
