The-relative volatility for separation of a non-ideal binary mixture by distillation should be ___________________?
Correct answer: C. > 1
- A. 0
- B. 1
- C. > 1
- D. < 1
Explanation
Distillation requires unequal volatilities, and relative volatility is conventionally defined as the volatility of the more volatile component divided by that of the less volatile component, so it must exceed one. A value of one indicates no volatility-based separation.
