Q80 / 200 · NEET 2012 (Screening) · Chemistry

In Freundlich adsorption isotherm, the value of $1 / n$ is

  • Correct answer
    A
    between 0 and 1 in all cases
  • B
    between 2 and 4 in all cases
  • C
    1 in case of physical adsorption
  • D
    1 in case of chemisorption

Solution

In Freundlich adsorption isotherm, $\frac{x}{m}=k p^{1 / n}$ the value of $n$ is always greater than 1. So, the value of $1 / n$ lies between 0 and 1 in all cases.

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