During an experiment in a laboratory, a sample containing chloroform (CHCl3) and acetone (C3H6O), two liquid substances miscible in any proportion, was subjected to gradual heating. In order to identify whether the mixture exhibits eutectic, azeotropic, or conventional behavior, the temperature variations and vapor pressures of the mixture in different states were recorded. Analyzing a graph that relates temperature to the vapor pressure of the mixture, it is observed that at 60°C, the measured vapor pressure is lower than the expected pressure for a conventional mixture with the same proportions of pure chloroform and acetone. Considering the properties of eutectic, azeotropic, and conventional mixtures, and the expected behavior of vapor pressures for each type of mixture, determine which of these behaviors the chloroform and acetone mixture exhibits, and explain your choice based on the phenomenon of freezing point depression characteristic of eutectic and azeotropic mixtures.
