For Freundlich adsorption isotherm, a graph of \(\log (x / m)\) vs \(\log (p)\) gives a straight line. The slope of line and its \(Y\)-axis intercept respectively are
- A \(\log \left(\frac{1}{n}\right) k\)
- B \(\frac{1}{n}, \log k\)
- C \(\log \left(\frac{1}{n}\right) \log k\)
- D \(\frac{1}{n}, k\)
Answer & Solution
Correct Answer
(B) \(\frac{1}{n}, \log k\)
Step-by-step Solution
Detailed explanation
We know that, Freundich adsorption
isotherm equation is given by
\(\log \frac{x}{m}=\log k+\frac{1}{n} \log p\)
Also equation of straight line is
\(y=m x+c\)
On comparing Eq. (i) and Eq. (ii), we get Slope, \(m=\frac{1}{n}\)
Intercept, \(c=\log k\)
isotherm equation is given by
\(\log \frac{x}{m}=\log k+\frac{1}{n} \log p\)
Also equation of straight line is
\(y=m x+c\)
On comparing Eq. (i) and Eq. (ii), we get Slope, \(m=\frac{1}{n}\)
Intercept, \(c=\log k\)
