Question

Select the incorrect statement. (A) Physical adsorption is reversible while chemical is irreversible. (B) High pressure favours physical adsorption while low pressure favours chemical adsorption. (C) Physical adsorption is not specific while chemical is highly specific. (D) High activation energy is involved in chemical adsorption.

Tardigrade Admin · Accepted Answer

Physical as well as chemical both the adsorptions are favoured by high pressure. However, the point of difference is that decrease in pressure causes desorption in case of physical adsorption but not in the case of chemical adsorption.
