Vedclass · Answer

(B) Adsorption is a surface phenomenon that depends on the surface area of the adsorbent. $1$. The adsorption process can be monolayered (chemisorption) or multilayered (physisorption). $2$. The particle size of the adsorbent significantly affects the amount of adsorption. Smaller particle size leads to a larger surface area,which increases the amount of adsorption. Therefore,the statement that particle size does not affect adsorption is false. $3$. According to Le Chatelier's principle,since physical adsorption is an exothermic process,an increase in temperature decreases the amount of adsorption. $4$. An increase in pressure generally increases the amount of gas adsorbed on a solid surface.
