Which of the following statement/s is/are not correctA. Physical adsorption is directly related to the critical temperature of the gas (adsorbate)B. One gram of charcoal at `25^(@)C` will always adsorb the same amount of a particular gas at a particular pressureC. At particular temperature, adsorption always increases with increase of pressureD. In adsorption, the concentration of adsorbate is always greater at the surface of the adsorbent

1.	Which of the following statement/s is/are not correctA. Physical adsorption is directly related to the critical temperature of the gas (adsorbate)B. One gram of charcoal at `25^(@)C` will always adsorb the same amount of a particular gas at a particular pressureC. At particular temperature, adsorption always increases with increase of pressureD. In adsorption, the concentration of adsorbate is always greater at the surface of the adsorbent
Answer» Correct Answer - B::C::D (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.
