Which of the Following Has the Lowest Vapor Pressure

Mercury exerts the lower vapour pressure because of the strong bond among its atom. For Urea solution C60100121000 2M.

Colligative Properties Relative Lowering Of Vapor Pressure Teaching Chemistry Chemistry Study Materials

A CsH2 b MgCl2 c CH-CH3NH2 d PBT e SOCI 4.

. Solutions have lower vapor pressures and therefore higher boiling points than pure solvents. Hence it will have lowest vapour pressure. Hence for Al2 SO4 3 Ci05525.

Answer 1 of 2. Which of the following should have the lowest boiling point. The line on the graph shows the boiling temperature for water.

The vapor pressure of pure water at 25C is 238 torr. According to the relative lowering of vapor pressurethe vapor pressure of a component at a given temperature is equal to the mole fraction of that component of the solution multiplied by the vapor pressure of. This means that the sodium chloride text textcolor c34632 sodium chloride sodium chloride solution will have the lowest vapor pressure.

This means that the concentration textbf concentration concentration of solutes will be greater in the case of sodium chloride. Here concentration of non-volatile solute is maximum for Al2 SO4 3. A CsH2 b CH24 c CHIA d C10H22 e C12H26 2.

The vapor pressure of a liquid varies with its temperature as the following graph shows for water. Which of the following should have the highest surface tension. So the higher vapor pressure it means that youll have a lower boiling point.

Its vapor pressure at 20C is 5896 kPa. The solution on the right left has had some of its solvent particles replaced by solute particles. Vapour pressure is the liquid property related to evaporation.

Match the vapor pressure diagrams with the solutesolvent combinations and explain your answers. Base your decision mainly on dispersion forces. Water is a polar liquid whose molecules are attracted to one another by relatively strong hydrogen bonding.

For example diethyl ether is a nonpolar liquid with weak dispersion forces. Thus the salt solutions will have lower vapor pressures than the pure water. ExplanationVapor pressure of mercury is very low compared to a liquid like methyl alcohol because the forces of interaction between the individual metal atom 20chem141 20chem141 13062021 Chemistry Secondary School answered Which of the following molecules has the lowest vapor pressure at 0 degrees C.

I believe the answer is CH3Cl but I am. The addition of a nonvolatile solute results in a lowering of the vapor pressure of the solvent. The vapor pressure of water at 20C is only 233 kPa far less than that of diethyl ether.

Which of the following should have the lowest vapor pressure. The 030 M NaCl has more solute than the 010 M NaCl Thus the 030 M NaCl will have the lowest vapor pr. At room temperature the substance with lowest boiling point will have the highest vapour pressure and the substance with highest boiling point will have the lowest vapour pressure.

Determine the vapor pressure of a solution at 25C that contains 766 g of glucose C6H12O6 in 2500 mL of water. So if were looking for the highest boiling point that means we want the lowest vapor pressure. Since the solute particles do not evaporate the vapor pressure of the solution is lower than that of the pure solvent.

A 708 torr B 729 torr C 231 torr D 229 torr E 729 torr. A CH32N b CH OCH c CH-CH2OH d CHCHF 3. As the temperature of a liquid or solid increases its vapor pressure also increases.

CHCl3 CH2Cl2 CH3Cl or CCl4. Of the following compounds which would you expect to have the lowest vapor pressure at room temperature. Stronger intermolecular forces LOWER vapor pressureWeaker intermolecular forces HIGHER vapor pressureCheck me out.

For Glucose solution C180100181000 1M. Because aluminum chloride dissociates to form the greatest number of dissolved solute particles the aluminum chloride solution will have the lowest vapor pressure. Cars used to be building as rigid as possible to withstand collisions.

Textbf lowest vapor pressure lowest vapor pressure. In this question youre looking at the relationship between vapor pressure and boiling point So vapor pressure is inversely proportional to boiling point. Today though cars are designed to have crumple zones that collapse upon impact.

Therefore the lithium bromide solution will contain 04 moles of dissolved ions per liter. The correct option is C 10 M. Solve any question of Solutionswith-.

So in this case this case were looking at acetic anhydride.
