Homework Problem 6L.1

Postby Victoria Zheng--2F » Wed Feb 19, 2020 10:34 pm

Hello. For the Homework problem 6L.1, how can I find the moles of the electrons transferred in the reaction, which is n for the equation deltaG=-nFEcell?

You have to look at all the oxidation numbers and find the oxidation and reduction agents. Then you see how many electrons were transferred and how the oxidation numbers change. Then you have to balance the half reactions so you can see how many total moles of electrons were transferred in the reaction.

It helps to separate the equation into its two half-reactions and balance both. When you do this, you're forced to think about how many electrons are transferred in order for the charges on both sides to be balanced, and from there you can plug in the number of moles of electrons into the equation you mentioned.
