    Assertion (A) : Atmosphere contains small amount of poisonous gases but they are preferably adsorbed on activated charcoal. Reason (R): On a particular adsorbent, the more strongly adsorbable adsorbate adsorbs to a greater extent than its partial pressure indicates.

    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. Preferential adsorption depends on strength of attraction, surface area, polar nature and other factors. Which of the following isomer of C_(6)H_(14) is adsorbed to maximum extent?

    Which gas is adsorbed strongly by charcoal ?

    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. Preferential adsorption depends on strength of attraction, surface area, polar nature and other factors. When temperature is increased in chemisorption then :
