Oh hi there, first post. I'm looking into electrochemical cells and using to the nernst equation to predict cell potential values, and came across a few threads on the topic already on this forum (although none really answered my question), so thought this would be the place to ask.

I know that at low concentrations the nernst equation does not give a very accurate prediction of cell potential. I'm struggling to find anywhere that will give me a good in depth explanation as to why.
So yeah, could anyone point me in the right direction, or just explain to me here? Also what other limitations are there to the nernst equation?
Thanks for any help

If you need details, check some serious source, like Electrochemistry by Hamann, Hamnett & Vielstich, or some equivalent book.

Don't really have 50 to spend on a book at the moment
Surely there must be some online sources I'm missing?

No idea about online sources - doesn't mean they don't exist.

If all else fails, try a library.
