Which of the following gases, will be adsorbed maximum on a solid surface?
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 ?
