Hi Borek,

Thanks a lot for your response!

I would really really appreciate it if you could help me set up Nernst equation for this one?

I set it as:

Delta E = RT/nF * ln([Fe3+ out]/[Fe3+ in])

and plugged in the values and got 0.0437 but the correct answer is 0.01459 so it must be wrong.

FYI

I plugged in:

R = 0.08206

T = 310

n = 1

F = 96485

[Fe3+ out] = 0.082

[Fe3+ in] = 0.016

but I am so lost.

Thanks a lot.
