Question

On which factor adsorption of gas on solid adsorbtion depend ?

• A. On temperature
• B. On nature of adsorbent
• C. On pressure of gas
• D. All of the above

Answer 1

The correct option is D All of the above

The surface area of a powdered solid adsorbent depends upon its particle size.

Smaller the particle size, greater is its surface area.

(i) An increase in the pressure of the adsorbate gas increases the extent of adsorption.

(ii) At low temperature, the extent of adsorption increases rapidly with pressure.

(iii) depends on the nature of adsorbent.

Hence, the correct option is $\text{D}$
