Arrhenius
e ea/rt - molecules that have enough energy to break activation barrier.
-
components
high temperature - you have 1/ infinity
e ^0 is 1
-
exponential
Endothermic break a bond ------- Exothermic Makes a bond

Clausius-Clapeyron, which is an exponential function
p = ae ( -H / rt )
-
ΔHvap,AΔHvap,A\Delta H_{vap,A} = Enthalpy of Vaporization for "A", always positive because it is endothermic
definition - energy needed to transfer one mole of substance into a gas
-
some will evaporate until it reaches its equilibrium
Equillibrium Vapor Pressure definition - rate of evaporation = rate of condensation.
-
That is, for molecules of similar mass, the stronger the intermolecular forces the lower the vapor pressure
The stronger the IM forces. The lower the vapor pressure.
