Question: 3 the vapor pressure data for benzene is given below...

Question details

3. The vapor pressure data for benzene is given below: Benzene 2.6 7.6 15.4 26.1 42.2 60.6 80.1 V.Р. (torr) 20 40 60 100 200 400 760 Using the vapor pressure data for benzene given here and the vapor pressure data for toluene in problenm no. 2, calculate: a) The enthalpy -xy (mole fractions) plot for the mixture at 1 atm b) Show the tie-lines on the enthalpy -xy plot corresponding to 90 °C and 105 °C. The enthalpy data is as follows: Saturated Enthalpy (KJ/Kg) Benzene Toluene Hy 487 511 537 HL T (°C) 60 80 100 79 116 153 471 495 521 114 151 Assume ideal mixture and be careful of the units. Enthalpy data at other temperatures can be obtained by fitting the given data using regression (can be done in Excel or MATLAB), and then interpolating or extrapolating it, as needed
