Document Summary
Chem112 lecture 11 vaporization and boiling point. If 0. 5 g of pure water is placed in a sealed 5 l flask and evacuated and heated to. 60oc, does the water evaporated: the vp for water is 149. 4 mmhg. 18 g = 0. 028 mol h2o: n=0. 5g. Boiling point: when vapor pressure is equal to the atmospheric pressure of 1 atm, this is. If the pressure is lower than the vapor pressure of a given molecule, then all of. If the pressure is higher than the vapor pressure of a given molecules, then only some will evaporate and the rest will remain as a liquid, with equilibrium reactions. Summary of effects for imf"s: the equilibrium vapor pressure decreases and consequently the liquid. In hindsight, a strong imf = high boiling point = low vapor pressure = high: for a liquid, as imf strength increases, the energy needed to vaporize the liquids will also increase, hvap increases boiling point increases.
