Question:

The following data are the equilibrium vapor pressure of limonene, C10H16, at various temperatures. (Limonene is used as a scent in commercial products.)Temperature (C) Vapor Pressure (mm Hg) 14.0 53.8 84.3 108.3 151.4 1.0 10. 40. 100. 400.

(a) Plot these data as ln P versus 1/T so that you have a graph resembling the one in Figure 11.13.
(b) At what temperature does the liquid have an equilibrium vapor pressure of 250 mm Hg? At what temperature is it 650 mm Hg?
(c) What is the normal boiling point of limonene?
(d) Calculate the molar enthalpy of vaporization for limonene using the Clausius–Clapeyron equation.


Data given in Figure in 11.13

Figure 11.13 Clausius-Clapeyron equation. This equation is named after the German physicist R. Clausius
