Try to answer these questions before determining the answer with the simulation. We suggest that you write down the reasons for your answers.

1. As batch distillation proceeds for a binary mixture without an azeotrope, does the temperature in the still increase, decrease, or remain the same?
2. For batch distillation of a binary mixture with a minimum boiling point azeotrope, does the composition of the distillate get to closer to or further away from the azeotrope composition?
3. In a batch distillation of 50/50 binary mixture without an azeotrope, can a significant amount of distillate be obtained with a mole fraction of the more volatile component greater than 0.95?
