Characteristics of Chemical Adsorption…

Characteristics of Chemical Adsorption –
(i) Chemisorption is highly specific and takes place at reaction centre on the adsorbent.
(ii) Surface area, temperature, nature of adsorbate effects chemisorption.
(iii) This type of adsorption is almost a single-layered phenomenon.
(iv) This type of adsorption is caused by chemical forces.
(v) It is a very strong process.
(vi) Energy of activation is very high 40 – 400 kJ/mol.
