The total vapor pressure of an ideal-dilute liquid mixture of acetone and chloroform with a mole fraction of acetone of 0.0500 is 45.08 kPa at 308 K. (a) Use Raoult's law to determine the partial vapor pressure of acetone for the mixture, given that the vapor pressure of pure acetone is 46.26 kPa at 308 K. (b) Hence calculate the partial vapor pressure of chloroform for the mixture. (c) Determine the Henry's law constant of chloroform at this temperature. (d} The Henry's law constant is lower than the vapor pressure of pure chloroform at 308 K. What does this imply about the nature of the interactions between acetone and chloroform in the liquid mixture?
