Liquid hexane at 298 K and 1 bar has the following properties: thermal expansion coefficient (B) = 5.2x10-4 K-1 isothermal compressibility (K) = 17.5x10-10 Pa-1 molar volume (v) = 1.30x10-4 m3/mole critical temperature (Tc) =507 K critical pressure (Pc) =29.7 bar Note: If you use scientific notation you must use upper case E for the exponent, e.g. 5.0E-3 = 0.0050 1. Calculate the change in molar volume if the pressure is increased from 1 bar to 30 bar at 298 K (m/mole). 2. Calculate the change in molar entropy if the pressure is increased from 1 bar to 30 bar at 298 K (J/mole-K). 3. Calculate the change in molar enthalpy if the pressure is increased from 1 bar to 30 bar at 298 K (J/mole). 4. Calculate the change in molar Gibbs energy if the pressure is increased from 1 bar to 30 bar at 298 K (J/mole). 5. Use the van der Waals equation to calculate the pressure required to contain 100 moles of hexane vapor in a volume of 0.0800 m at 600 K. (bar).
