What are the key differences between adsorption and absorption?
Absorption | Adsorption |
1. It is a bulk process. | 1. It is a surface phenomenon. |
2. It is an endothermic process. | 2. It is an exothermic process. |
3. The absorption reaction takes place at a uniform reaction rate. | 3. In adsorption, the reaction rate increases gradually and eventually attains equilibrium. |
4. No change in concentration takes place. | 4. In the reaction, the concentration at the bottom of the absorbent is distinct from the bulk. |
5. Temperature does not affect the process. | 5. The process takes place at a lower temperature. |
6. The process of absorption is applied to ice production, cold storage, and turbine inlet cooling. | 6. The process of adsorption is applied in air conditioning, in the synthesis of resin, and water purification. |
