What does the nr variable represent in the Nernst Equation?

nr is essentially the molar coefficient (in this case, the number of moles of e- transferred); nr is unitless

Reference: P. 429

If you were confused with the subscript, page 571 says, "The subscript r is always the signal that we are using this 'molar' form."

nr is the molar coefficient of the Nernst Equation. It is basically the number of moles of electrons transferred.

Be sure to remember with nr that the unit "mol" isn't incorporated

It is the total amount of electrons transferred. This can be found by combining two half reactions for the redox reactions.

To find the moles of electrons transferred, you'll want to look at the two balanced half reactions and make sure that the electron change is same in both.
