A rigid, closed vessel of volume V =648 liters maintained at constant temperature T=365 K is loaded with 112 mol of n-hexane, 155 mol of n-heptane, and 14 mol of nitrogen. Calculate the pressure in the vessel and the composition of all phases present at equilibrium. Make the following three assumptions: a) n-hexane and n-heptane form an ideal liquid solution, b) the vapor phase is ideal, c) nitrogen has negligible solubility in the liquid phase at the conditions of interest. The vapor pressures of n-hexane and n-heptane at T=365 K are P1=0.199 MPa and P2=0.083 MPa, respectively. Their (liquid) molar volumes are VĀÆ 1=0.146 l/mol and VĀÆ 1=0.162 l/mol, respectively.
