alleryChemisorption involves compound formation, so it is usually:
AUnspecific
BEndothermic
CIrreversible
DReversible
Answer & Solution
Correct answer: C. Irreversible
1. A chemical bond forms between adsorbate and adsorbent.
2. Breaking that bond again is not easy.
3. So chemisorption is usually irreversible.
