The vapor pressure of a substance is measured over a range
Chapter 11, Problem 8SAQ(choose chapter or problem)
The vapor pressure of a substance is measured over a range of temperatures. A plot of the natural log of the vapor pressure versus the inverse of the temperature (in Kelvin) produces a straight line with a slope of -3.46 x 103 K. Find the enthalpy of vaporization of the substance.
a) 2.40 x 10-3 kJ/mol
b) 28.8 kJ/mol
c) 0.416 kJ/mol
d) 3.22 kJ/mol
