14.37

I understand how to plug all the values into the NERNST equation after I write the half reactions, but I'm confused as to where the solutions manual is getting 0.025693V/n. I thought we were supposed to use either 2.303RT/nF or 0.0592/n?

The equations that you mentioned (2.303RT/nF and 0.0592/n) is with LOG of Q while the solution manual uses LN of Q. Therefore, all three of these equations are actually equivalent. Hope that clarifies it!

.025693 V is R * 298.15 K / F.
