The boiling point decreases as the vapour pressure increases.

### How do atmospheric pressure and elevation affect boiling point? | Socratic

Just as with gases, increasing the temperature shifts the peak to a higher energy and broadens the curve. Some molecules at the surface, however, will have sufficient kinetic energy to escape from the liquid and form a vapor, thus increasing the pressure inside the container.

As the number of molecules in the vapor phase increases, the number of collisions between vapor-phase molecules and the surface will also increase.

Eventually, a steady state will be reached in which exactly as many molecules per unit time leave the surface of the liquid vaporize as collide with it condense. At this point, the pressure over the liquid stops increasing and remains constant at a particular value that is characteristic of the liquid at a given temperature. The rate of evaporation depends only on the surface area of the liquid and is essentially constant.

The rate of condensation depends on the number of molecules in the vapor phase and increases steadily until it equals the rate of evaporation. Equilibrium Vapor Pressure Two opposing processes such as evaporation and condensation that occur at the same rate and thus produce no net change in a system, constitute a dynamic equilibrium.

In the case of a liquid enclosed in a chamber, the molecules continuously evaporate and condense, but the amounts of liquid and vapor do not change with time.

The pressure exerted by a vapor in dynamic equilibrium with a liquid is the equilibrium vapor pressure of the liquid. If a liquid is in an open container, however, most of the molecules that escape into the vapor phase will not collide with the surface of the liquid and return to the liquid phase.

One is some vapor in equilibrium with the solution.

### Boiling point - Wikipedia

Another is pure water, and the last is the vapor it equilibrates with. Let's imagine we were wrong about how solutes affect vapor pressure, and the vapor pressure above the solution were more than the vapor presure above the water.

Higher pressure gas has higher mu.

Boiling, Atmospheric Pressure, and Vapor Pressure

That would mean that water would spontaneously flow from the solution to any region of pure water. So the solution would spontaneously separate into a pure water region and a denser region. So it wasn't in equilibrium to begin with. So our assumption that you could have, in equilibrium, higher vapor pressure above the solution is self-contradictory.

## 11.5: Vapor Pressure

If a compound's vapors are not contained, then some volatile compounds can eventually evaporate away in spite of their higher boiling points. Boiling points of alkanesalkenesethershalogenoalkanesaldehydesketonesalcohols and carboxylic acids as a function of molar mass In general, compounds with ionic bonds have high normal boiling points, if they do not decompose before reaching such high temperatures.

Many metals have high boiling points, but not all. Very generally—with other factors being equal—in compounds with covalently bonded moleculesas the size of the molecule or molecular mass increases, the normal boiling point increases. When the molecular size becomes that of a macromoleculepolymeror otherwise very large, the compound often decomposes at high temperature before the boiling point is reached.

Another factor that affects the normal boiling point of a compound is the polarity of its molecules.

As the polarity of a compound's molecules increases, its normal boiling point increases, other factors being equal.
