Homework 14.17

Postby Jared Smith 1E » Fri Mar 16, 2018 11:06 pm

I'm having a little bit of trouble understanding this question. How exactly would we determine the half reactions given only the reactant? We would just look at the table in the back to see which reactions involve that reactant, or is there something I'm missing?

Yes, it seems as though the half reactions are the ones in the back of the book. This question seems to function a lot like Lavelle's test that had the reduction reactions in the back of the test and you had to look at them to compute voltage and understand the reaction taking place. However, I do not know if there is some other technique that you may use and if any of the Chem admins could give you tips other than "Look at the back of the book", I would probably listen to them.

I attached my work:

I wrote down the potentials for all the possible 1/2 reactions, and found the pair that summed to the most +, since this is a galvanic cell (E>0). Then you just balance and add them. :)
