1. Write a MATLAB function file that would take input values for the Antoine's equation constants, and Temperature; and will output values of x and y vs P to plot P-xy phase diagrams. Use this function file to prepare the phase diagrams of problem 10.2. Note: you may also want to create a function file where the input variables are A,B,C and P and the output are values of x,y, and T to create Txy phase diagrams. 0.2. Assuming Raoult's law to be valid, prepare a P - xy diagram for a temperature of 90 ' C and a t+xy diagram for a pressure of 90kPa for one of the following systems: (a) Benzene(1)/ethylbenzene(2): (b) 1-Chlorobutane(1)/ehlorobenzene(2)
