Which of the following is/are correct about Freunlich’s adsorption isotherm for gases and solutions?

\(\frac{\mathrm{x}}{\mathrm{~m}}=\mathrm{KC}^{1 / \mathrm{n}}\)
\(\frac{x}{m}=\frac{1+b P}{a}\)
\(\log \left(\frac{\mathrm{x}}{\mathrm{~m}}\right)=\log \mathrm{K}+\mathrm{n} \log \mathrm{P}\)
\(\log \left(\frac{x}{m}\right)=\log K+\frac{1}{n} \log C\)

Answer

(A) x ~m = KC ^ 1 / n, (C) ( x ~m )= K + n P, (D) ( x m )= K+ 1 n C
