In McCabe-Thiele method, at infinite reflux ratio___________________?
Correct answer: C. Both the operating lines coincide with the diagram
- A. Number of plates is maximum
- B. Overhead product is maximum
- C. Both the operating lines coincide with the diagram
- D. None of these
Explanation
At infinite reflux, no products are withdrawn, so both rectifying and stripping operating lines approach the diagonal y = x. This represents total reflux and gives the minimum number of theoretical stages.
