If a mixture is distilled rapidly, the separation of its compound is poorer than if the mixture is distilled slowly. Please explain why is that so using your own understanding. I don't need a copy-pasted answer from google.

3. A sealed glass vial is prepared with 4 mL of air and 36 mL of water. Trichloroethylene (TCE) is added to the water to create an initial aqueous phase concentration of 100 ppb (a) (b) After the system equilibrates, what will the concentration of TCE be in the aqueous phase (in µg/L)? Determine the % mass partitioning of TCE between the water and the air when equilibrium is established. (c) If a quantity of TCE is accidentally spilled into a well-mixed river, where would you expect most of the TCE to end up in the short term - in the air or in the water? Explain.

Pls do fast within 5 minutes and i will give like for sure Solution must be in typed form To plan a liquid–liquid extraction we need to know the solute’s distribution ratio between the two phases. One approach is to carry out the extraction on a solution that contains a known amount of solute. After the extraction, we isolate the organic phase and allow it to evaporate, leaving behind the solute. In one such experiment, 1.235 g of a solute with a molar mass of 117.3 g/mol is dissolved in 10.00 mL of water. After extracting with 5.00 mL of toluene, 0.889 g of the solute is recovered in the organic phase. If we extract 20.00 mL of an aqueous solution that contains the solute using 10.00 mL of toluene, what is the extraction efficiency?
