Steady state equimolal counter diffusion is encountered in_____________________?
Correct answer: A. Separation of a binary mixture by distillation
- A. Separation of a binary mixture by distillation
- B. Absorption of NH3 from air by water
- C. All liquid-liquid diffusion systems
- D. All liquid-solid diffusion systems
Explanation
Binary distillation commonly involves equimolal counterdiffusion because the molar liquid and vapour flow rates remain approximately constant through the column. Ammonia absorption into water is not equimolal because the solvent is essentially nonvolatile.
