A liquid solution containing 49 moles of benzene and 21 moles of toluene is slowly heated to 363 K and a pressure of 1:013 × 105 Pa in a closed container.
a. What would be the composition of the liquid phase and the gas phase in equilibrium at 363 K and 1:013 × 105 Pa? At 363 K, the vapor pressure of benzene is 1:344 × 105 Pa and the vapor pressure of toluene is 5:38 × 105 Pa.
b. Determine the amount of liquid that would be present after this mixture is heated to 363 K.
