What are the key differences between adsorption and absorption?
|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.|
