After carrying out reflux and distillation to produce ethyl ethanoate (ethyl acetate) I measured the boiling point and I got 71 degrees Celsius whereas the true value is 77.1 degrees Celsius. Impurities increase the Boiling point (BP) as well as concentration. However my calculates BP is lower than the … WebThe partial vapor pressure of a component in a mixture is equal to the vapor pressure of the pure component at that temperature multiplied by its mole fraction in the mixture. Raoult's Law only works for ideal mixtures. In equation form, for a mixture of liquids A and B, this reads: (1) P A = χ A P A o. (2) P B = χ B P B o.
