Physisorption |
Chemisorption |
|
1. |
In physisorption, the adsorbate is attached to the surface of the adsorbent with weak vander Waal’s forces of attraction. |
In Chemisorption, strong chemical bonds are formed between the adsorbate and the surface of the adsorbent. |
2. |
In physisorption, no new compound is formed in the process. |
By chemical reaction, new compounds are formed on the surface of adsorbent |
