For the adsorption of a solute from a liquid solution onto a solid adsorbent, the empirical Freundli — Surface Chemistry Chemistry Question
Question
For the adsorption of a solute from a liquid solution onto a solid adsorbent, the empirical Freundlich equation takes the modified form $\frac{x}{m} = kC^{1/n}$. Which of the following factors influence the numerical values of the constants $k$ and $n$?
Answer: A,B,C
💡 Solution & Explanation
The empirical constants $k$ and $n$ are highly dependent on the nature of the solid adsorbent (porosity, surface area), the temperature of the system, and the nature of the solute/solvent pairing. They do not depend on the sheer volume of the holding container as long as the equilibrium concentration $C$ is known.
