In case of absorption & stripping, the interface of the liquid & gas phases are present in equilibrium, when the diffusional resistance of _______________ is zero?
Correct answer: C. Interface
- A. Liquid phase
- B. Gas phase
- C. Interface
- D. All A , B. & C.
Explanation
The gas and liquid compositions are assumed to be in equilibrium at their common interface when interfacial resistance is negligible. The main resistances then lie in the gas and liquid films, not at the interface itself.
