According to Freundlich adsorption isotherm, which of the following is correct ?

Multiple Choice Options

  • A xm∝p0{x \over m} \propto {p^0}
  • B xm∝p1{x \over m} \propto {p^1}
  • C xm∝p1/n{x \over m} \propto {p^{1/n}}
  • D All the above are correct for different ranges of pressure

Step-by-Step Verified Solution

The Freundlich adsorption isotherm is mathematically represented as

xm=kP1/n{x \over m} = k{P^{1/n}}

at high pressure 1n{1 \over n} = 0 Hence, x / m∝p∘x\,/\,m \propto {p^ \circ }

at low pressure 1n{1 \over n} = 1 Hence, x/m  ∝  p′x/m\,\, \propto \,\,p'
