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

Options

  1. Axm∝P0\frac{x}{m} \propto P^0
  2. Bxm∝p1\frac{x}{m} \propto p^1
  3. Cxm∝p1/n\frac{x}{m} \propto p^{1 / n}
  4. DAll the above are correct for different ranges of pressure

Correct answer

D. All the above are correct for different ranges of pressure

Step-by-step solution

xm∝P0\frac{\mathrm{x}}{\mathrm{m}} \propto \mathrm{P}^0 is true at extremely high pressures xm∝p1;xm∝p1/n\frac{x}{m} \propto p^1 ; \frac{x}{m} \propto p^{1 / n} are true at low and moderate pressures.
