You are watching: Which of the following factors affect the vapor pressure of a liquid
i m sorry of the following determinants does not impact the vapor press of a liquid? (A) Concentration the solutions, (B) volume that the liquid, (C) temperature, (D) intermolecular forces.
Our score in this inquiry is to identify which that the answer selections does not have actually an impact on the vapor push of a liquid. The vapor push of a fluid is the equilibrium press exerted through the vapor on the surface ar of the liquid phase. The vapor above the surface of the liquid is developed by the procedure of evaporation. In a closed container in ~ a particular temperature, the amount of vapor above the surface ar of the liquid remains consistent over time.
let’s imagine water is within this closed container. The amount of vapor, and also therefore the vapor pressure, remains constant over time, due to the fact that the price of evaporation is same to the rate of condensation. If a aspect or readjust disrupts this equilibrium by boosting or diminish the evaporation rate, climate a brand-new equilibrium will need to be established. And the vapor pressure might be larger or smaller. To solve this problem, us will need to read every answer an option carefully and also determine if the factor results how easily molecules in a liquid can escape the surface to kind a vapor.
Intermolecular forces determine the strength of the pressures of attraction between molecules in a liquid. Evaporation can only occur if the intermolecular forces between molecules in the liquid space overcome and also the fluid molecules escape native the surface of the liquid to become vapor. A fluid with more powerful intermolecular forces will not evaporate as quickly as a liquid v weaker intermolecular forces. This means that liquids with stronger intermolecular forces tend to have actually lower vapor push than liquids through weaker intermolecular forces. Intermolecular pressures are a variable that influence the vapor push of a liquid. Therefore, us can remove answer choice (D).
Now, let’s consider answer choice (C). Boosting the temperature of a liquid boosts the kinetic energy of the molecules in the liquid. This means the rate of evaporation will boost because more molecules in the fluid phase will absorb enough energy to get over the intermolecular forces that organize them together. The vapor press of the fluid will rise with temperature because the price of evaporation is increasing. Due to the fact that temperature is a factor that influence the vapor push of a liquid, us can eliminate answer an option (C).
Now, let’s discuss answer an option (A) concentration of solutions. When a solute is added to a liquid, such together by dissolving sugar in water, the evaporation process slows down. This is because the liquified solute corpuscle interfere through the evaporation process. If the concentration that the solution is boosted by adding much more solute, then the vapor press will to decrease further. Since the concentration of a solution does impact the vapor push of a liquid, we can remove answer choice (A).
Finally, let’s discuss answer an option (B) the volume the the liquid. If us were come add much more liquid come a container already holding a liquid, the price of evaporation would more than likely not change. This is since we have actually not changed the area of the surface of the liquid, i beg your pardon is wherein evaporation takes place. If we boost the volume and the area of the surface of the liquid, climate the price of evaporation would increase. However, the price of condensation would additionally increase due to the bigger surface area. Due to the fact that the rate of evaporation and the rate of condensation readjust by the exact same degree, the vapor pressure of the liquid does not change.

The factor which walk not affect the vapor push of the liquid is, therefore, the volume that the liquid, or answer selection (B).
