At minimum reflux ratio for a given separation__________________?
Correct answer: B. Number of plates is infinity
- A. Number of plates is zero
- B. Number of plates is infinity
- C. Minimum number of the theoretical plates is required
- D. Separation is most efficient
Explanation
At minimum reflux, the operating line touches the equilibrium curve, creating a pinch point where an infinite number of theoretical stages would be needed for the specified separation. Finite reflux above the minimum is required for a finite column height.
