A8. For a typical straight-chain hydrocarbon, does:
K=y/x
x=mole fraction of methanol in Liquid
y=mole fraction of methanol in gas
a. K increase, decrease, or stay the same when temperature is increased?
If the problem should be assumed the constant pressure(∆P=0),the K value^'

D1. A very large distillation column is separating p-xylene (more volatile) from o-xylene. The column has two feeds (similar to Figure 4-17, but without the side stream). Both feeds are saturated liquids. Feed 1 is 42mol% p-xylene, F1=90 kmole/hr. Feed 2 is 9mole % p-xylene, F2=20 kmole/hr. The bott

D1. A continuous, steady-state distillation column with a total condenser and a partial reboiler is separating methanol from water at one atmosphere (See Table 2-7 for data). The feed rate is 100 kg mole per hour. The feed is 55 mole % methanol and 45 mole % water. We desire a distillate product tha
