To evaluate the Wilson parameters from the activity coefficients in an infinitely dilute binary solution, nomographs have been prepared which show the following features of the Wilson equation.
i. In a system of positive deviations from ideal behaviour only I set of parameters exists.
ii. In a system of negative deviations, I through 3 sets of parameters satisfy the Wilson equation. By these nomographs, the authors have evaluated the Wilson parameters for the acetone-chloroform system, which give a good representation of the data.
