The difference between the vapour pressure of solvent above swollen crosslinked polyurethanes and that above linear polyurethane solutions has been determined experimentally. Comparison of the data over a range of volume fractions of solvent has enabled an estimate to be made of the factor B/A, the...
The vapour pressure of a solvent decreases by 5.4 torr when a non-volatile solute is added. In this solution, mole fraction of solute is 0.2. What would be mole fraction of the solvent if decreases in vapour pressure is 16.2 torr ?
As the attractive forces between the molecules of a liquid increase, its equilibrium vapor pressure at a given temperature: A. remains the same. B. decreases. C. increases. Generally, the vapor pressure of a liquid is related to: ...
The boiling point of a solution will ___ and the vapor pressure will ___ with a(n) ___ in the amount of dissolved solute. (increase/decrease) Study on the effect of the addition of solute to the solvent on its boiling point and ...
However, supercritical CO2 requires costly high-pressure equipment (65 bars) and ionic liquids are very expensive and are lacking a commercially viable recycling process At the same time, solvent-extraction of furfural and acetic acid from the acidic evaporated condensate, originating from the spent...
Sections “Solvents and solvency” and “Solvents use, waste and pollution” provide a brief introduction to solvents, their uses and their impact. Section “Solvent replacements” introduces solvent replacement methods for the reduction of such impact, followed by “Solvents and sustainability” section...
Assertion (A) : The vapour pressure of a solution containing non-volatile solute is less than the vapour pressure of pure solvent . Reason (R) : In the case of a solution of a non-volatile solute, some of the surface positions are occupied by the solute. ...
vapour pressure- the pressure exerted by a vapor; often understood to mean saturated vapor pressure (the vapor pressure of a vapor in contact with its liquid form) vapor pressure force per unit area,pressure,pressure level- the force applied to a unit area of surface; measured in pascals (SI...
