Barium Nitrate is a not very soluble nitrate. Calculate the Ksp (at 25 degrees) from the following ΔG's: Ba2+ = -561kj/mole NO3 1- = - 109kj/mole Ba(NO3)2 = - 797 kj/mole I did the first step and I ended up with dGrxn = -127 kj/mol. When I plugged it into the second ...

I am working on the same problem. I did the first step DrBob gave and I ended up with dGrxn = -127 kj/mol. When I plugged it into the second equation I got -127000/(-298)(8.314) = 51.2599. Then if I take the e of this I get 1.8x10^22. I feel like this is way off, since the ...
