can we believe the results of Flory-Higgins parameter (chi) from Blends model?

Hi,

Can we believe the results of Flory-Higgins parameter (chi) from Blends model? I used the Blends Model to calculate the Flroy-Higgins parameters(see below)

Chi (298 K)

Emix (298 K)

Chi1=Emix/RT

Chi/Chi1

19.1136031

11.31883754

0.00456852

4183.762

9.02913065

5.34693864

0.002158137

4183.762

19.41521064

11.49744577

0.00464061

4183.762

10.22602798

6.05572632

0.002444218

4183.762

19.44074124

11.51256467

0.004646712

4183.762

10.51929541

6.22939564

0.002514315

4183.762

Based on the manual,  χ(chi)=Emix/RT, in fact I find the results (see the third column) that will be multiplied 4183.762, which can equal to the results (the first column) from the automatic results.

Who can tell me, How to compute the chi parameter in Blends model?

Thank you!
