One-Constant Margules To Represent Benzene - 2,2,4 - Trimethyl pentane

  1. Apr 1, 2010 #1
    In the book, "Chemical, Biochemical, and Engineering Thermodynamics", 4th Edition - Stanley I. Sandler, Univ. of Delaware

    On Pg. 435,the diagram (Fig 9.5-4) has been provided, which has been attached as a file. This represents the experimental activity coefficient data for the "benzene-2,2,4 trimethyl pentane mixture" and the correlation of these data obtained using the One-Constant Margules equation.


    Illustration 9.5-1 asks to test the accuracy of the One-Constant Margules equation in correlating these data.

    In the solution of this question, the book says that

    I'm extremely confused as to why this diagram (Fig 9.5-4) is not considered to be a mirror image ?


    A similar Figure (attached as fig2) has been described by the author as a mirror image. I consider both these diagrams to be identical


    I hope someone can clarify my confusion
