They are inversely related. The volatility of a liquid increases with decreasing vapor pressure, as it provides more reversible effect on liquid molecules, so less liquid molecules are able to escape. Conversely, the volatility of liquid increases with decreasing vapor pressure, as it provides less reversible effect on liquid molecules, allowing more to escape.

What is equilibrium vapor pressure?
It is vapor molecules in equilibrium with a liquid in a closed system exert a pressure proportional to the concentration of molecules in the vapor state.
What does the vapor pressure of water at 10 C compare with its vapor pressure at 50 C?
At higher temperature the vapor pressure is higher.
Is increase of vapor pressure a colligative property?
The lowering of the vapor pressure is a colligative property.
Which of the colligative properties is not dependent on vapor pressure boiling point elevation vapor pressure reduction osmotic pressure?
Osmotic pressure.
What statements is true about vapor pressure?
The vapor pressure of 1 m sucrose (C12H22O11) is higher than the vapor pressure of 1 m NaCl where the solvent is water Sea water has a lower vapor pressure than distilled water. The vapor pressure of 0.5 m NaNO3 is the same as the vapor pressure of 0.5 m KBr, assuming that the solvent in each case is water The vapor pressure of 0.10 m KCl is the same as the vapor pressure of 0.05 m AlCl3 assuming the solvent in each case is water The vapor pressure of 1 m NaCl is lower than the vapor pressure of 0.5 m KNO3, assuming that the solvent in each case is water The vapor pressure of 0.10 m NaCl is lower than the vapor pressure of 0.05 m MgCl2 assuming the solvent in each case is water.
What is the relationship between the rate of evaporation and the rate of condensation of the vapor of a liquid in a closed container and has a constant vapor pressure?
In a system at constant vapor pressure, a dynamic equilibrium exists between the vapor and the liquid. The system is in equilibrium because the rate of evaporation of liquid equals the rate of condensation of vapor. -KarkatHorns
What is difference between vapor pressure and vapor density?
I do not now
What is the relationship between pressure and the boiling points of liquid?
As atmospheric pressure increase so does the boiling pont, when atmos. pressure decreases so does boiling point. A liquid boils when its vapor pressure equals atmospheric pressure.
What is the relationship between water vapor and altitude?
as altitude inscreases, water vapor level decreases
What is the relationship between the temperature and dew point?
Dew point is the temperature at which the water vapor in the air condenses, then evaporates. The barometric or air pressure is independent from the dew point.
Explain how the attractive forces between the particles in a liquid and the equilibrium vapor pressure of that liquid related?
The weaker the intermolecular forces, the easier the liquid evaporates. Higher vapor pressure the faster it evaporates. Thus, the weaker the attractive forces, the higher the vapor pressure and vice versa.
The difference between vapor pressure of a pure solvent and its partial pressure?
vapor pressure of a pure solvent is the pressure needed for the gas to escape the pure solvent in vapor form. its partial pressure in this case will be the pressure of that escaped vapour (in the mixture of air). in simpler terms vapor pressure describes a single condensable system (just the vapor of the solvent and the liquid state of the solvent) while its partial pressure describes the multicomponent system (air). they are essentially the same thing describing different systems
What is equilibrium vapor pressure?
It is vapor molecules in equilibrium with a liquid in a closed system exert a pressure proportional to the concentration of molecules in the vapor state.
What does the vapor pressure of water at 10 C compare with its vapor pressure at 50 C?
At higher temperature the vapor pressure is higher.
What will a hydrate do if its vapor pressure is higher than the vapor pressure of the water vapor in the air?

Is refrigerant leaving a compressor in a cars air conditioning system high pressure vapor high pressure liquid or low pressure vapor?
high pressure vapor
What is crude oil true vapor pressure?
True Vapor Pressure is the pressure of the vapor in equilibrium with the liquid at 100 F (it is equal to the bubble point pressure at 100 F)
