What is E not and how is it different from E?

E not refers to the standard state potential. This means the potential of the cell is approximated under standard conditions- at 25 Celcius and with concentrations of 1 mole per liter (1 M). I think regular E is just... not at those conditions?... that's how I understood it at least.

Edit: looked it up- E is the cell potential when the reaction is not at equilibrium.

According to Lavelle's lecture, E not is the standard reduction potential and gives voltage difference between two standard electrodes which are always the same, as in these values are empirically predetermined and can be found on a table. Ecell is the cell potential but I don't think it can be empirically determined with specificity.
