Question
The extent of adsorption of a gas on a solid depends on :
The extent of adsorption of a gas on a solid depends on :
Open in App
Solution
The correct option is D all of the above
The extent of adsorption of a gas on a solid depends on :
(A) nature of the gas (adsorbate)
Easily liquefiable gases are readily adsorbed than gases that do not liquefy easily.
(B) pressure of the gas
With increase in pressure, the extent of adsorption increases.
(C) temperature of the gas
Increase in temperature will decrease the extent of adsorption as adsorption is exothermic process.
(D) nature and surface area of the adsorbent.
Greater is the surface area of the adsorbent, greater is the extent of adsorption.
