The vapor pressure for pure water and pure acetone is measured as a function of temperature. In each case, a graph of the log of the vapor pressure versus 1>T is found to be a straight line. The slope of the line for water is -4895 K and the slope of the line for acetone is -3765 K. Determine ΔHvap for each substance. Account for the difference by discussing the molecular structure of the two molecules.
