Question
Chapter 4.4, Problem 5E
Interpretation Introduction
Interpretation: Drastic reduction of fractional distillation if heat is supplied to stillpot too rapidly should be explained.
Concept introduction: Fractional distillation is separation technique that separates various fractions of components in mixture. This process is based on vaporization of one or more fractions or parts of mixture. It is used to separate components of mixture that have difference in boiling points less than
