JEE Main Chemistry question

Not in JEE Main or NEET syllabus

Rate of physical adsorption increases with

(A)Decrease in surface area
(B)Decrease in temperatureCorrect
(C)Increase in pressure
(D)Increase in temperature

Answer: (B)

Solution

Physical adsorption is favoured by a larger surface area, so a decrease in surface area (A) does not increase it. Being an exothermic process, physical adsorption is favoured by lower temperature and falls as temperature rises, so an increase in
