In Freundlich adsorption isotherm at moderate pressure, the extent of adsorption (xm)\left( {{x \over m}} \right) is directly proportional to Px. The value of x is :

Multiple Choice Options

  • A ∞\infty
  • B zero
  • C 1
  • D 1n{{1 \over n}}

Step-by-Step Verified Solution

According to Freundlich adsorption isotherm, in the median range of pressure

xm∝P1n{x \over m} \propto {P^{{1 \over n}}}

⇒\Rightarrow    xm{x \over m} = kP 1n^{{1 \over n}}

Hence, x = 1n{{1 \over n}}
