Q3. (25) Carbon dioxide is absorbed in water at

20\\\\deg C

and

1atm

in a packed column. For this system it may be assum that

98%

of the resistance to mass transfer occurs in the liquid film and the overall coefficient is

K_(y)^(')=0.95kmo(l)/(s)*m^(2)*m

frac. For dilute solution of carbon dioxide in water, the equilibrium curve can be expressed in terms of the Henry' Lat constant by

P_(A)=1.42\\\\times 10^(-3)x_(A)

where

P_(A)

is the partial pressure of

A

in the gas film in atm,

x_(A)

is the mole fraction in thi liquid, and the Henry's law constant has units, atm/mole fraction. Assuming equimolar counter diffusion calculate the followings\ a)
