Q. If xD = overhead product molal composition and RD = reflux ratio, then slope and intercept of the operating line for rectifying section are respectively (Solved)
1. [xD/(RD + 1)], [RD/(RD + 1)]
2. [RD/(RD + 1)], [xD/(xD + 1)]
3. [xD/(RD + 1)], [(RD + 1)/RD]
4. None of these
- b. [RD/(RD + 1)], [xD/(xD + 1)]
