a

A pressure vessel of 5 litre internal volume contains a mixture of n-pentane and n- hexane. The following information on the pure component properties is provided. The pressure and temperature in the vessel are 200 kPa and 68.7 °C, respectively and it is known that both liquid and vapour phases are present in the vessel and the system obeys Raoult's law. Calculate the Molar composition of the liquid phase present in the vessel. Component n-Pentane n-Hexane Molar Mass (kg/kmol) 72 86 Normal Boiling Point (°C) 36.1 68.7 n-pentane=45 mol % & n-hexane-55 mol% n-pentane=55 mol % & n-hexane=45 mol % n-pentane=57 mol% & n-hexane=43 mol% n-pentane=61 mol % & n-hexane-39 mol% Latent Heat of Vaporization (MJ/kmol) 25.77 29.04
