Using the Nernst quation calculate the following EMF of these cells at the non standard states Cu(II)-Zn(II) Fe(II)-Zn(II) Pb(II)-Zn(II) please show work. i dont understand especially calculating Q using the nernst equation. Why are the non standard states cell potenials the same as the standard state cell potenials
