1.	Which of the following statement/s is/are not correct
Answer» Physical adsorption is directly related to the critical temperature of the gas (adsorbate) ONE gram of CHARCOAL at `25^(@)C` will always adsorb the same AMOUNT of a particular gas at a particular pressure At particular temperature, adsorption always increases with increase of pressure In adsorption, the concentration of adsorbate is always greater at the surface of the adsorbent Solution :(B) is wrong because adsorption depends upon the surface area. (c) is wrong because at about `0^(@)C`, adsorption remains constant after a particular pressure. (d) Is wrong because there can be negative adsorption also.
