For part A of question 4 on the 2013 final, can we also use Ecell = Ecello - 0.05916/n * logQ instead of Ecell = Ecello - RT/nF * lnQ ?

I get a slightly bigger answer when I use the Nernst equation with log in it than the one with ln.

Generally, you should use the log equation when also looking for pH. Otherwise, I think it is easier to use the natural log.

Does it seem that we will be deducted for using one equation versus the other if pH is not a factor?
