In the absorption of ammonia in water, the main resistance to absorption is by the _________________ phase?
Correct answer: B. Gas
- A. Liquid
- B. Gas
- C. Both A. & B.
- D. Neither A. nor B.
Explanation
Ammonia is highly soluble in water, making the liquid-film resistance relatively small; the gas film usually provides the main resistance to absorption. This is why ammonia absorption is commonly treated as gas-film controlled.
