The extent of adsorption decreases with an increase in temperature

Vedclass · Answer

(C) . The extent of adsorption increases with an increase in temperature is an incorrect statement because an increase in temperature reduces the interaction between the solute and adsorbent molecules.$B$. The extent of adsorption decreases with an increase of surface area of the adsorbent is an incorrect statement as $	ext{Adsorption} \propto 	ext{surface area of adsorbent}$.$C$. The extent of adsorption decreases with an increase in temperature.$\because 	ext{Adsorption} \propto \frac{1}{	ext{temperature}}$.Thus,this is the correct statement.$D$. The extent of adsorption does not depend on the amount of solute in solution is an incorrect statement because $\frac{x}{m} \propto C^{1/n}$,where $\frac{x}{m}$ is the amount of solute adsorbed per unit mass of adsorbent and $C$ is the concentration of the solute. Thus,the plot of $\log(\frac{x}{m}) 	ext{ vs } \log C$ gives a straight line with a positive slope.Hence,option $C$ is the correct answer.
