Degree of freedom increases, as

A. Reflux increases

B. Purity decreases

C. Purity increases

D. Reflux decreases

This question was posed to me during an interview.

This is a very interesting question from Problems When Setting Simulation Input in portion Rigorous Distillation Calculations of Distillation Design

The correct answer is C. Purity increases

The best explanation: Degree of freedom increases as Purity increases, as they are ditrectly proportional also this can be related using phase rule F =C –P+2.
