Answer #1

Effect of temperature and kinetic energy on solubility : As the temperature of the solution increaese the average kinetic energy of the solution also increaese. This increase in kinetic energy allow the solvent molecules to more effectively break the solute molecules and hence solubility increases.

Effect of pressure on solubility : Pressure affects the solubility of gas dissolving in a liquid but it never affects the solubility of solid and liquid.

Effect of solute surface area : Solubility of solid in a liquid increases with increase in surface area. More surface area means solid is to be broken into smaller peices. For example, a sugar cube will dissolve slower than an equal amount of tiny peices of sugar crystals.

Therefore, pressure does not affect the solubility of solids in a liquid.

Let’s consider the solubility of a gas in a liquid, specifically carbon dioxide in water. We know that the solubility of a gas in a given solvent increases with pressure (think about an unopened soda). In many gas absorption processes (e.g., stripping, scrubbing) we will want to add or remove a solute from/to a gas phase. We want to calculate the solubility of CO2 in H2O, as a wt%, at a CO2 partial pressure of 200 kPa in the gas...

1-True or False The solubility of gases in liquids increases with increasing pressure. 2-True or False An aqueous solution containing a nonvolatile solute such as sucrose will boil above 100°C at 1 atm pressure. 3-True or False The solubility of KBr at 20°C is 60 g/100 g H2O. Increasing the temperature of the solution will likely increase the solubility of KBr.

Which of the following statements correctly characterizes the rate of evaporation of a liquid?       I. Increases with increasing temperature because molecules have higher kinetic energies.       II. Increases with increasing surface area of the liquid because more molecules are located at the surface.       III. Decreases with stronger intermolecular forces because molecules are less able to escape from the surface of the liquid. II only III only I only I and II only All three: I, II, and III

Solids soaked with liquid hexane are dried by being contacted with nitrogen at an elevated temperature. The gas stream leaving the dryer is at 80°C, 1 atm absolute and 50% relative saturation. (a) One of several possibilities for recovering the hexane from the gas is to send the stream to a cooling condenser. The gas stream leaving the condenser would contain 5.00 moles of hexane (out of 100 total moles), and hexane condensate would be recovered at a rate of...
