The assumption made in Elis method in distillation is that enthalpy concentration lines of vapor and liquid are __________________?
Correct answer: C. Both parallel and straight
- A. Parallel
- B. Straight
- C. Both parallel and straight
- D. Neither parallel nor straight
Explanation
The Ellis distillation approximation treats the vapour and liquid enthalpy-concentration relationships as straight, parallel lines. This is why both geometric assumptions appear together in option c.
