Answer the following questions: a. Why will the area of heterogeneity decrease if the temperature increases in extraction? b. Why is a centrifugal extractor best suitable for extraction in a system having a very low-density difference?  c.  Why should you use liquid extraction in heat-sensitive materials with the very high latent heat of vaporization? d.  Why is LLE extraction based on the difference in solubility? e. Why is solvent extraction the unit operation by which soluble components of a liquid mixture are dissolved in a liquid that is partially immiscible with the other components? f. Why is there more distribution coefficient if in an extraction process the greater the weight of the solute in the raffinate relative to that in the extract?
