Two film theory applies for absorption of a solute from a gas mixture into a liquid solvent. The interfacial mass transfer coefficient (in mol [VISUAL / REVIEW — NO INVENTED LATEX] Source math clip

for the gas side is 0.1 and for the liquid side is 3. The equilibrium relationship is

y*=2x

, where xandy *are mole fractions of the solute in the liquid and gas phases, respectively. The ratio of the mass transfer resistance in the liquid film to the overall resistance is

Options

A.
0.0161
B.
0.0322
C.
0.0625
D.
0.0645

Answer

Solution

k ₓ=3 k _y=2

y = 0.1x

.

.

⇒ 1/3 + 1/0.2 ⇒ 0.34 + 5

.

.

Hence, the correct options is (C).
