Question

Can you please answer sub question A through C and show all of the steps to the solution 

A. Labeling all the parts, draw a sketch of the distillation set-up used by you, and answer the
following: (a) Why the inlet of cold water should be at the lower end of the condenser and (b)
Why the thermometer bulb should be below the arm of the distillation head connected to the
condenser?
B. If liquid A boils at 353 K and liquid B boils at 403 K, which liquid would have higher
vapor pressure at room temperature?
C. How does energy (heat) input into a system affect the vapor pressure of a liquid?
D. Explain what is meant by 'normal boiling point' in terms of vapor pressure of a liquid vis-a-
vis temperature.
E. What is the difference between the terms "refluxing" and "distillation"? Do both the
processes take place at the same temperature?
