Correct equation of Freundlich isotherm is

  • Correct answer
    A
    \(\log \left(\frac{x}{m}\right)=\log k+\frac{1}{n} \log c\)
  • B
    \(\log \left(\frac{x}{m}\right)=\log c+\frac{1}{n} \log k\)
  • C
    \(\log \left(\frac{x}{m}\right)=\log c+\frac{1}{k} \log c\)
  • D
    \(\log \left(\frac{x}{m}\right)=\log k+\frac{1}{k} \log c\)

Solution

The empirical relation, viz., $\frac{x}{m}=k c^{1 / n}$, put forward by Freundlich is known as Freundlich's adsorption isotherm. Taking $\log$ on both sides $\log \left(\frac{x}{m}\right)=\log k+\frac{1}{n} \log c$

Hence, the correct answer is option: 'A'.
