For the binary system of ethanol (component 1) and benzene (component 2), find the pressure at which the first bubble will form and the vapor phase composition of an equimolar mixture at 323 K: A. Using the two-parameter Margules equation: A12=2.173; A21=1.539 B. Assuming ideal solution

Use the Peng-Robinson EOS to estimate each of thefollowing properties of propylene.A. The vapor pressure at T = 25°C.B. The fugacity at the critical point.C. The fugacity of saturated liquid at T = 25°C.D. The fugacity of compressed liquid at T = 25°Cand P = 500 bar.E. The normal boiling point.

Prompt/Given Information: Consider a reversible isothermal expansion of vapor benzene at 450 K from 1 to 0.1 MPa. Assume that the PVT behavior of benzene obeys van der Waals equation of state.                                      P = (RT)/(V - b) - a/V2            for benzene: a = 1884514 (cm6 * MPa)/mol2 and                                  b = 119.47 cm3/mol For your convenience, at 450 K and 0.1 MPa the volume of vapor benzene is 37025 cm3/mol, and at 450 K and 1 MPa it is 3312.4 cm3/mol. R = 8.314 (MPa*cm3)/(mol*K). Note: 1 cm3*MPa/mol = 1 J/mol   Question: What is the change of internal energy? What would be the change of internal energy if the gas was ideal?

To find out the equilibrium vapor phase molar composition and pressure, use a liquid binary solution containing 4 moles of tert-butanol (1) and 14 moles of iso-butanol (2) at 363.15 K. Apply Raoult's law in VLE.
