Which one of the following gives a straight line for Freundlich adsorption isotherm?

  1. A \(\log \frac{x}{m} v s \log p\)
  2. B \(\frac{x}{m} v s \frac{1}{p}\)
  3. C \(\log \frac{x}{m} v s \log \frac{1}{p}\)
  4. D \(\frac{x}{m} v s p\)
Verified Solution

Answer & Solution

Correct Answer

(A) \(\log \frac{x}{m} v s \log p\)

Step-by-step Solution

Detailed explanation

Freundlich adsorption isotherm is as \(\frac{x}{m}=K p^{1 / n}\) Taking logarithms on both sides \(\log \frac{x}{m}=\log K+\frac{1}{n} \log p\) On plotting a graph between \(\log x / m\) and \(\log p\), a straight line will be obtained.
