by k 12 = 0.092. 4.49 You wish to use the Redlich-Kwong equation of state to describe a mixture of carbon dioxide (1) and toluene (2). To be as accurate as possible with the mixing rules, you want to include the binary interaction parameter, k12. In the literature, you find reference to an experiment with the following conditions: ni n2 V 2.0 mol 3.0 mol 10.0L 400.0 K 1.353 MPa T Using the data above and critical point property data, estimate k12. ture of benzene and propane
