McCabe-Thiele method of binary distillation does not assume that the__________________?
Correct answer: D. None of these
- A. Sensible heat changes are negligible compared with latent heat changes
- B. Molar latent heats of all components are equal
- C. Heat of mixing is negligible
- D. None of these
Explanation
The McCabe-Thiele method uses constant molar overflow, which assumes negligible sensible-heat and heat-of-mixing effects and approximately equal molar latent heats. Therefore, all three listed assumptions apply, making “None of these” correct.
