Dr. Parkhurs,
Thank you very much for your prompt response. For exchange species activity is
equivalent fractioons which is explained in page 12 of manual.
{activity} = Gama*be*ne/Te
However, I could not understand it. I think it is not just matter of mol/L
and mol/kg.
The reason is I tried to simulate and could get the matching output with
significantly different Log K values.
With Regards,
Tirtha
