Which of the following is not a characteristic of chemisorption?
Options
- AH is of the order of 400 ~kJ
- BAdsorption is irreversible
- CAdsorption may be multimolecular layer
- DAdsorption is specific
Correct answer
C. Adsorption may be multimolecular layer
Step-by-step solution
Chemisorption is highly specific and will not form if there is no possibility of chemical bonding between adsorbent and adsorbate. Chemisorption doesn't form multimolecular layer and hence, option (c) is incorrect.
