Question

What form Freundlich adsorption equation will take at high pressure?

✓

Answer

Freundlich Adsorption Isotherm, $\frac{\text{x}}{\text{m}}=\text{kp}^\frac{1}{\text{n}}$At high pressure (beyond saturation pressure), $\frac{1}{\text{n}}=0\ \text{and}\ \frac{\text{x}}{\text{m}}=$constant i.e., the adsorption is independent of pressure. So,
$\frac{\text{x}}{\text{m}}=\text{kp}^0\ \ \text{or}\ \ \frac{\text{x}}{\text{m}}=\text{k}.$
