Rayleigh's equation applies to _________________ distillation?
Correct answer: C. Differential
- A. Continuous
- B. Steam
- C. Differential
- D. Flash
Explanation
Rayleigh's equation describes differential or batch distillation, where the still liquid composition changes continuously as vapour is withdrawn. Continuous and flash distillation use steady-state material-balance methods instead.
