. Chemisorption is while physical adsorption is in nature
A: reversible, reversible
B: irreversible, reversible
C: reversible, irreversible
D: irreversible, irreversible
Best Answer
Explanation:
- Chemisorption is an adsorption type in which adsorbate is grasped to the adsorbent by strong chemical bond.
- Chemical adsorption (Chemisorption) involves compound formation by covalent or ionic binding which are irreversible in nature.
- Chemisorption involves high activation energy.
- Physical adsorption (Physisorption) is an adsorption of gas on solids occurring in terms of weak van der Waal’s forces.
- Physisorption of gas on solids is generally reversible.
Final answer:
Hence, the correct option is B: i.e. irreversible, reversible
