Calculate the vapor pressure at 80 C of a mixture of 35 mol % hexane and 65 mol % heptane.

Calculate the vapor pressure at 80 C of a mixture of 35 mol % hexane and 65 mol % heptane. Calculate the mol fraction of each compound in the vapor in equilibrium with the mixture in (1). If a simple distillation were to be performed on this mixture( from question 1 ), what would be the composition of the initial distillate? Suppose the mixture was to be distilled using a very efficient fractional distillation column. what would the composition of...
