Question

The phenomenon of adsorption find its application in

• A. Production of high vacuum
• B. Heterogeneous catalysis
• C. Curing diseases
• D. All of the above

Answer 1

The correct option is D All of the above

Adsorption is the accumulation of molecular species at the surface rather than in the bulk of a solid or liquid.

Application of adsorption:
1. In curing disease: Some medicines are surface active and their primary step of action of curing is adsorption over the pathogen surface.

2. Heterogeneous catalysis: Adsorption of reactants on the solid surface of the catalysts​ increase the rate of the reaction

3. When vessel evacuated by a vacuum pump, there will be some traces of air which can be removed by adsorption on charcoal to obtain very high vacuum.
