Vedclass · Answer

(B) The statement in option $B$ is incorrect because both physisorption and chemisorption can occur at various pressures depending on the nature of the adsorbent and adsorbate. Physisorption is generally favored at low temperatures and high pressures,while chemisorption often requires activation energy and can occur at higher temperatures.
