A popular commercial solvent mixture is made up of several aliphatic and aromatic hydrocarbons.You are tasked with estimating its properties assuming toluene is the main component.You are expected to solve this problem in two ways, a) using the Lee-Kesler diagrams to estimate the following quantities. A) The molar volume at the critical point.B) The molar volume in the liquid phase at T = 110C and P = 10 bar.C) The molar volume in the vapor phase at T = 310C and P = 20 bar.D) The change in molar enthalpy when toluene is heated and compressed from T = 110C andP = 10 bar to T = 310 C and P = 20 bar.Note: you may use PREOS and other Excel spreadsheets, but only as a calculator

Consider the 1-hexene (1) 1 n-hexane (2) systemat 328.15 K. Using Raoult’s Law, predict the systempressure and vapor-phase composition for thismixture and provide a Pxy plot for this mixture.Compare the results of your modeling with the setof experimental data provided for this system inTable P10-16. Plot the data (as points) on the sameplot as your model. Is this system properly modeledby Raoult’s Law? Why or why not?
Question 3 A vapour-liquid mixture of water (1) and furfural CSH4O2 (2) is maintained at 1.013 bar and 109.5 °C. Under these conditions, it is found that x1 = 0.10 and y1 = 0.81. The temperature of the mixture %3D is changed to 100.6 °C, and some (but not all) of the vapour condenses. The vapour phase may be assumed to behave as an ideal gas. The liquid-phase activity coefficients are independent of temperature but vary with concentration according to the van Laar equations. Determine: (a) The activity coefficients for water and furfural at 1.013 bar and 109.5 °C [9%] (b) The van Laar constants [6% ] Vapour pressure data: T=1006°C, Pa =1.0352 bar, Pl= 0.1193 bar T=109.5°C, Psal -14088 bar, Pal -0.1690 bar %3D
