Nernst

Postby CHEM 14B Lover » Tue Mar 12, 2019 7:41 pm

Is n the total number of e- moved after balancing the half reactions?

Yes, n is the number of moles of of e- transferred in the redox reaction.

Yes, it is the amount of electrons released in a balanced galvanic reaction

yes, the total n is referring to the amount of electrons transferred in the balanced redox reaction.

Yes, it must be for a balanced redox reaction.

Yup, you find total e- after you balance the reaction.

Yes--after balancing the redox reaction and finding the intermediate electrons transferred, you use this number of electrons as 'n,' as they are the moles of electrons.

Yes, if you have a balanced reduction half rxn and balanced oxidation half rxn, they will both tell you the number of e- transferred.

do you think we have to know how to derive the nernst equation for our final?

Outline 5 says "Know how to derive the Nernst equation and use it to calculate the cell potential as a function of concentration" so I'm pretty sure.

Just making sure, n could never equal 0 since there is always a transfer of electrons right?

Yes I think so
