The extent of adsorption of adsorbate from the solution phase increases with ________.
(i) increase in the amount of adsorbate in solution.
(ii) decrease in surface area of the adsorbent.
(iii) increase in temperature of the solution.
(iv) decrease in the amount of adsorbate in solution
The answer is the option (i).
The molecular species that get adsorbed on the surface is known as adsorbate. With an increase in the amount of adsorbate, both the interaction of adsorbent and the extent of adsorption increase.
Increase in the amount of adsorption in solution as an amount. As the amount of adsorbate in the solution increases the interaction of adsorbate with the adsorbent increases which led to increase in the extent of adsorption.
Correct option is A)
