If the value of the binary interaction parameter is k12=0.1, determine the values of the Peng-Robinson parameters am and bm that you would use to model a vapor phase mixture composed of 65 mol% component 1.

A pair of compounds, identified as 1 and 2, have the following properties:



You have five known VLE data points at 325 K. Your task is to generate the Pxy diagram describing all VLE mixtures of these compounds at 325 K, using phi-phi modeling and the Peng-Robinson equation.


Solve for the cross-parameter for ‘a’ using the binary interaction parameter:





Solve for am:
