This is handy because the knowledge that you should have from 1st semester redox chemistry should allow you to review the table and not have to much trouble at all thinking about why the values are on which side and correspond with other values below and above and why the values change for electyrolytic cells. And in senior chem where I made the table it helped me to first understand.
