The individual mass transfer co-efficients (moles/m2s) for absorption of a solute from a gas mixture into a liquid solvent are, KL = 4.5 and KG = 1.5. The slope of the equilibrium line is 3. Which of the following resistance (s) is (are) controlling ?
Correct answer: B
Explanation
The controlling resistance is the one with the smaller mass transfer coefficient (KG = 1.5 < KL = 4.5).
