Whenever a mixture of gases is allowed to come in contact with a particular adsorbent under the same conditions, the more strong adsorbate is adsorbed to greater extent irrespective of its amount present, e.g. H_(2)O is adsorbed to more extent on silica gel than N_(2) and O_(2). This shows that some adsorbates are preferentially adsorbed. It is also observed that preferentially adsorbable adsorbent can displace a weakly adsorbed substance from the surface of an adsorbent. When temperature is increased

1.	Whenever a mixture of gases is allowed to come in contact with a particular adsorbent under the same conditions, the more strong adsorbate is adsorbed to greater extent irrespective of its amount present, e.g. H_(2)O is adsorbed to more extent on silica gel than N_(2) and O_(2). This shows that some adsorbates are preferentially adsorbed. It is also observed that preferentially adsorbable adsorbent can displace a weakly adsorbed substance from the surface of an adsorbent. When temperature is increased
Answer» extent of ADSORPTION increases extent of PHYSICAL adsorption decreases no effect on adsorption extent of physical adsorption first decreases, then increases Answer :B
