Which one of the following statements is correct for adsorption of solutes on solids in solutions?

Options

  1. AThe extent of adsorption increases with an increase in temperature
  2. BThe extent of adsorption decreases with an increase of surface area of the adsorbate
  3. CThe extent of adsorption decreases with an increase in temperature
  4. DThe extent of adsorption does not depend on the amount of the solute in solution

Correct answer

C. The extent of adsorption decreases with an increase in temperature

Step-by-step solution

(a) The extent of adsorption increases with an increase in temperature is an incorrect statement because an increase in temperature reduces the interaction between the absorbate molecules and adsorbent molecules. (b) The extent of adsorption decreases with an increase of surface area of the adsorbate is also an incorrect statement as adsorption surface area of adsorbate. (c) The extent of adsorption decreases with an increased in temperature. Adsorption 1 temperature Thus, is the correct statement. (d) The extent o
