QUES : How adsorption help in production of vaccum?​

Answer 1

Answer:

Adsorption help in following phenomenon: (i)Production of high vacuum: Traces of air can be adsorbed by charcoal from a vessel, evacuated by a vacuum pump to give a very high vacuum. (ii)Heterogeneous catalysis:The gaseous reactants are adsorbed on the surface of the solid catalysts.
