Is anyone else having trouble calculating the concentration of Fe2+ in Endgame 2D?
I have all the right numbers for each variable (checked on the answer key), and I'm using Nernst Equation, but every time I somehow manage to calculate wrong??
Please help I feel like I'm about to lose my mind.

Hi nevermind but leaving this here in case someone else is having trouble too.
I forgot to add a negative sign before I simplified further than lnQ.
I'm losing my mind.

Maybe double check the numbers you're using again? when I do 0.15*-2*96485/(8.314*298) I get the right answer

How? I am doing the same calculation and I keep getting lnQ= -11.6. And for the concentration of Fe 2+ I get 9.2 x 10^-6. I've gone through the problem several times and I keep getting this answer
