Criss Cobble Extrapolation

[JamesV]

Hi,

I am having trouble figuring out how the criss cobble extrapolation is being done in version 7.0. For example the Ni(+2)/Ni(OH)2 equilibrium does not seem to change with increasing temperature from 298 K to 323 K when it used to change in version 4.0 and from my calculations it should change. Does anyone know what might be going on, is there an example of the HSC Chemistry Criss Cobble calculations somewhere. It would be helpful if I knew what dG they are using for H2O(l) and H(+a) at elevated temperature... I am in the process of trying to figure this out so any comments would be welcome.

Thanks,

James
