Physisorption of a gas on a solid surface is characterised by which kind of force?
AWeak van der Waals forces
BStrong ionic attraction
CMetallic bond formation
DCovalent bond sharing
Answer & Solution
Correct answer: A. Weak van der Waals forces
Physical adsorption involves only weak van der Waals attraction, so it is easily reversible.
