At the same time, the rate at which water molecules in the vapor phase collide with the surface and reenter the solution is unaffected. If the temperature and vapor pressure are known at one point, along with the enthalpy of vaporization, Hvap, then the temperature that corresponds to a different vapor pressure (or the vapor pressure that corresponds to a different temperature) can be determined by using the Clausius-Clapeyron equation (Equation \(\ref{10.4.1}\)) : Since the normal boiling point is the temperature at which the vapor pressure equals atmospheric pressure at sea level, we know one vapor pressure-temperature value (\(T_1\) = 80.1 C = 353.3 K, \(P_1\) = 101.3 kPa, \(H_{vap}\) = 30.8 kJ/mol) and want to find the temperature (\(T_2\)) that corresponds to vapor pressure P2 = 83.4 kPa. \end{align*}\].

Explain these vapor pressures in terms of types and extents of IMFs for these alcohols: All these compounds exhibit hydrogen bonding; these strong IMFs are difficult for the molecules to overcome, so the vapor pressures are relatively low. This is almost the situation with a mixture of ice and water in a very good thermos bottle; almost no heat gets in or out, and the mixture of solid ice and liquid water remains for hours.
