Find the distillate and the residue rates in mole/hr, if the feed rate...
Ans.

Method to Solve :

F*xf= D*xd+ W*xw
On applying the values, we get distillate rate= 64 mol/hr and residue rate is 36 mol/hr

Find the distillate and the residue rates in mole/hr, if the feed rate...
Given data:
Feed rate = 100 mol/hr
Mole fraction of feed = 0.65
Mole fraction of distillate = 0.9
Mole fraction of residue = 0.2

We can use the material balance equation to find the distillate and residue rates:

Feed rate = Distillate rate + Residue rate

Distillate rate = Feed rate x Mole fraction of distillate
= 100 x 0.9
= 90 mol/hr

Residue rate = Feed rate - Distillate rate
= 100 - 90
= 10 mol/hr

Therefore, the distillate rate is 90 mol/hr, and the residue rate is 10 mol/hr.

Option B: 64,36 is incorrect.
