(5pts.) 1. Define HETP and give the word associated with each letter in the acronym.
(6pts.) 2. In a fractional distillation you started with 100 of solution in your kettle. During the
procedure your temperature rose to 57 degrees C and remained steady for 25 ml of product
collection, then rose to 83 degrees C for 45 ml of product collection, then rose to 111 degrees C for 25
ml of product collection. What is the liquid volume percentage of each of these components
collected?
(5pts.) 3. Notice that in question two above you lost 5 ml of the mixture; which one of the
components would you expect exhibit the most prominent loss during the distillation?
(4pts.) 4. Fill in the following table with correct numerical value that corresponds to one atmospheric
pressure.
