Which of the following statements is incorrect regarding chemisorption?
- A.It is highly specific in nature.
- B.It involves high heat of adsorption.
- C.It is a reversible process.
- D.It involves the formation of chemical bonds.
Show correct answer & step-by-step solution
Correct answer: C — It is a reversible process.
Solution
- Chemisorption involves strong chemical bonds between adsorbate and adsorbent.
- Due to these strong bonds, the process is typically irreversible.
- Physisorption is reversible, whereas chemisorption is not.
- Therefore, the statement that it is reversible is incorrect.
- Hence the answer is (C).
