In a binary system, separation is very efficient, when the relative volatility is_______________?
Correct answer: B. > 1
- A. 1
- B. > 1
- C. < 1
- D. 0.5
Explanation
Relative volatility greater than one indicates that the more volatile component is enriched in the vapour phase, making separation possible. A value of one means both components have equal volatility and ordinary distillation cannot separate them.
