A) directly proportional to pressure
B) inversely proportional to pressure
C) directly proportional to square of pressure
D) independent of pressure
Correct Answer: D
Solution :
At high pressure, the extent of adsorption\[\left( \frac{x}{m} \right)\]becomes constant as the adsorbent surface is saturated with the adsorbate. Hence,\[\frac{x}{m}\]becomes independent of pressure. Mathematically,\[\frac{x}{m}=kp{}^\circ \].
