Question

According to Freundlich adsorption isotherm

• A. \( \frac{x}{m} = k p^{1/n} \)
• B. \( \frac{m}{x} = k p^{1/n} \)
• C. \( x m = k p^{1/n} \)
• D. \( \frac{x}{m} = \frac{k}{p^{1/n}} \)

Hint:

The Freundlich isotherm equation is commonly used to describe adsorption phenomena, and it is applicable for non-ideal adsorption where the surface is heterogeneous.

Answer 1

The Correct Option is A

Step 1: Understanding the Freundlich Adsorption Isotherm.
The Freundlich adsorption isotherm describes the relationship between the amount adsorbed (\(x\)) and the equilibrium pressure (\(p\)). The equation is given by: \[ \frac{x}{m} = k p^{1/n} \] where \(x\) is the mass of adsorbate, \(m\) is the mass of the adsorbent, and \(k\) and \(n\) are constants. Step 2: Conclusion.
The correct answer is (A), as it correctly represents the Freundlich adsorption isotherm.
