Vedclass · Answer

(C) $1$. Physical adsorption (physisorption) is multilayered due to weak van der Waals forces.$2$. Chemical adsorption (chemisorption) is irreversible because it involves the formation of strong chemical bonds.$3$. Physical adsorption is an exothermic process; therefore,it decreases with an increase in temperature. It does not increase first.$4$. Langmuir adsorption isotherm is primarily used to describe chemisorption,where a monolayer is formed on the surface.
