Test: Surface Chemistry - 2 (Old NCERT) - Question 15
Save

Which is correct in case of Vander waals adsorption?

Detailed Solution: Question 15

Physiadsorption is favoured only at low temperature and high pressure.

Test: Surface Chemistry - 2 (Old NCERT) - Question 16
Save

Which adsorption takes place at low temperature?

Detailed Solution: Question 16

Physical adsorption is favoured at low temperature because it involves only vanderwall interactions between adsorbate and adsorbent.

Test: Surface Chemistry - 2 (Old NCERT) - Question 17
Save

Pt and Pd adsorb large volume of hydrogen under specific conditions. The hydrogen so adsorbed is called?

Detailed Solution: Question 17

Adsorption of hydrogen by metal like Pt is occlution and hydrogen is known as occluded hydrogen.
