Calculate the vapor pressure of butanol (b.p. 117 C) at the gas chromatography column temperature of 95.0 C using the form of the Clausius-Clapeyron equation shown vap In @)--(e) G ) G. =- 1 T 1 T2 R where R is the ideal gas constant, AH yap is the enthalpy of vaporization, T, and T2 are two different temperatures, and Pi and P2 are the vapor pressures at the respective temperatures. The enthalpy of vaporization can be estimated using Trouton's rule, AHvap = (88 J.mol-!. K-') x Typ 285.7 P= Torr Incorrect Calculate the vapor pressure of pentane (b.p. 36.0 C) at the same column temperature. 1289.5 P= Torr Incorrect
