Hi Brian,
It seems that I already used most of the 500K upload quota and hence can't upload anymore. But here is the thermodata for enargite (using the same data posted by FTA (fernando) on this website) that I incorporated into my thermodata file in accordance with the required format.
Enargite type= enargite
formula= Cu3AsS4
mole vol.= 88.350 cc mole wt.= 393.7996 g
6 species in reaction
3.000 Cu+ 1.000 As(OH)4- 4.000 SO4--
-5.000 H2O -7.500 O2(aq) 6.000 H+
465.4360 414.1113 362.0154 312.9855
263.9463 221.6313 186.0364 156.4474
I used the GUI to select the species. I don't know how to pull the script from elsewhere (did not use command tab)
Here is what I did:
I diagrammed Cu+ on Eh-pH (or O2(aq)-pH) axes, added As(OH)4- and SO4-- under the "in the presence of".
I assumed activity for all the species as 0.001.
Thanks & regards,
Suma
