  4. Assertion: The relation (x/m)=k ⋅ p1 / n is known as Freundlich adsorption isotherm, where ' x ' is the mass of gas adsorbed by ' m ' grams of adsorbate, ' p ' is the equilibrium pressure, k and n are constants for given system and temperature. Reason: When several substances have same value of (1/n), the lines by which their adsorption isotherms can be represented will meet at a point.

Q. Assertion : The relation $\frac{x}{m}=k \cdot p^{1 / n}$ is known as Freundlich adsorption isotherm, where ' $x$ ' is the mass of gas adsorbed by ' $m$ ' grams of adsorbate, ' $p$ ' is the equilibrium pressure, $k$ and $n$ are constants for given system and temperature.
Reason : When several substances have same value of $\frac{1}{n}$, the lines by which their adsorption isotherms can be represented will meet at a point.

Surface Chemistry

Solution:

Assertion is true, reason is false. When several lines have the same value of $\frac{1}{n}$, then the lines by which their adsorption isotherms can be represented will be parallel and will not meet at a point.
