A gas mixture containing 85.0 mole % N2 and the balance n-hexane (C6H14) flows through a pipe at a rate of 100.0m3/h. The pressure is 2.0 atm absolute and the temperature is 100C. (a) What is the molar flow rate of the gas in kmol/h ? (b) Prove that the gas is not saturated with the hexane. (c) What temperature \( (\varangle \mathrm{C}) \) would the gas have to be cooled to at constant pressure to start to condense the hexane? (d) If the gas is cooled at constant pressure and 80% of the hexane in the gas is condensed what is the value of the equilibrium vapour pressure of the hexane in the gas (mmHg)
