Tedit, adding a mineral, Log K formation or reaction?

Recommended Posts

Howdy, 

I need to add new minerals to the thermo-database because I am working with some odd-ball ones not in there yet.  

I am want to clarify that the log Ks that need to be entered with each mineral in Tedit, are the reaction Log K, not the formation log K, correct? 

Thank you very much,

Danielle

Hi Danielle,

Reactions in the GWB's thermo datasets are written as destruction reactions (i.e., a mineral breaks down to basis species instead of basis species forming a mineral). You supply the log K for the reaction as it's written.

Hope this helps,

Thank you very much, Brian,

Yes, I think this helps, I'll now have to check the papers to see if this info is published.

Thank you for responding,

Danielle
