Dear Expert,
I am trying to conduct Gibbs Free Energy Direct Minimization Calculations using Excel spreadsheet.I am following the procedures published in the attached PDF file. However, I am facing a problem in the initial estimate described in the paper (Highlighted in Yellow). In fact,I'm not able to understand how the author is solving that problem and how to implement it in my excel file.

Hi Said.
Attached you find the Excel workbook with the corrections and some tips for get the solution.
That I think the problem has two answers: One answer is a local minimim, the other one is another minimum. Probably Both answers are ok, but thermodinamically maybe will be posible. This is not my best field.
I Think that will be useful
Good luck
