Which statement is correct about chemisorptions?

Question

Which statement is correct about chemisorptions? (A) It is irreversible in nature (B) It involves formation multi layer of adsorbent on adsorbate (C) Decreases with increase of temperature (D) It involves the weak attractive forces between adsorbent and adsorbate

Tardigrade Admin · Accepted Answer

Chemical adsorption is irreversible due to formation of new strong chemical bonds. It is unilayer due formation of new chemical bonds. It first increases with increase in temperature due to supply of energy of activation then decreases due to breaking of covalent bond.
