Question

A. during distillation, there are two reasons why the temperature will sometimes go down rather than up. what are the two possible causes?

B. during a destillation experiment of 1:2 ethyl acetate to n-butyl acetate, which component of the mixture will be the greater component of teh vapor phase vs. the liquid phase? explain

Answer 1

A) Answer:

During thre distillation process, The liquid becomes in to vapour and it condence in to liquid as a drops while passing through the condenser.

1) According to the GayLussac's law the pressure is directly praportional to the Temperature.

During the condensation of the vapour the accumilation of the vapour takes place and the temperature shows more. While the condensation is going the vapour pressure is decreases in the condenser and the Teperature also decreases.

2) If the kinetic energy of the molecules increases, The temperature decreases.

B) Answer:

Ethyl acetate boiling point = 77 C

n-Butyl acetate boiling point = 126 C.

The Boiling point of the Ethyl acetate is less hence its vapour phase and the liquid phase both are more during the distillation process.
