### Nernst Equation usage

I am still confused on when we would need to use the Nernst Equation? Like what kind of questions would be asked that would prompt us to use the equation?

The Nernst equation relates the energy of a cell outside of standard conditions when the concentrations of the products and reactants change to energy in standard conditions. So, when there is a change in concentration, use the Nernst equation.

What is the Nernst equation exactly?

The Nernst equation calculates cell potential based on concentration. It is E.

The Nernst Equation relates cell potential to the concentration of what is being reduced and oxidized in their aqueous solutions.

You'd use it to relate the reduction potential (under non-standard conditions) to the standard electrode potential. At any point in the reaction, you can find the cell potential using this equation.

Oh this is the one similar to the delta g equation comparing the delta g at standard and delta g given?
