HOMEWORK 3: A gas from is separated the mixture consisting of A and B components in
the absorption column. A specific bulk gas concentration in the tower is 70% (as mole fraction)
and bulk liquid concentration is 10% (as mole fraction). The tower is operating at 30 ° C and 1
atm and the equilibrium data are as follows:
xA

0.10
0.20
0.25
0.30
