Could someone explain what we use Nernst Equation for and how it relates to cell potential and concentration?

It describes how cell potential (the direction of electron transfer) depends on concentration under non-standard conditions. So, we could use the Nernst equation to solve that example about gold dissolving in nitric acid if we were given non-standard conditions (not 1M).

The nernst equation is describing the cell potential, which the direction where the electron goes, and how it depends on concentration under different conditions.
