I think I must have Ecell to calculate pK (or concns of all of the reagents).
E cell is not given, just the E0 cell which is -1.133V
That will be
ln K = nFEo>sub>cell/RT
Use 8.314 for R, 298 for T, 96,485 for F. Calculate K, then convert to pK.
ln K = nFEo>sub>cell/RT should read
ln K = nFEocell/RT
what is "n"
and thank you so much for all the help!
Isn't n = 10?
Cl2 ==> 2ClO3^-
zero on the left to +10 (for both Cl atoms) on the right.
10 on the left (for 5 Cu^+2) and zero on the right.
Total 10 either way.
with n=10, im getting an answer of 0 when I do e^(k)
My calculator reads 2.38 x 10^-192.
i tried that, apparently its not the right answer either =/.
The question asks for pK. 2.38 x 10^-192 is K. pK = -log K = -log 2.38 x 10^-192.
