adsorption is essentially

appreciable
At lower temperature?
Answers
Answer:
Physical adsorption is performed at low temperatures by a weak bonding force called van der Waals. The heat released from this adsorption does not exceed 5 kcal/mol. This adsorption increases with increased gas pressure and decreases with high temperature. The gas is more absorbent as it is easy to liquefy.

Answer:
mark me as brainliest plze daerrrr
Explanation:
Since the adsorption process is exothermic, the physical adsorption occurs readily at low temperature and decreases with increasing temperature (Le-Chatelier's principle). Porous substances are better adsorbents as an increased surface area promotes adsorption. Does not require energy for activation.
