Question

Assertion :The relation $\frac{x}{m}=k.p^{1/n}$ 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 the same value of $\frac{1}{n}$, the lines by which their adsorption isotherms can be represented will meet at a point.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
• B. Both Assertion and Reason are correct, but Reason is not the correct explanation for Assertion.
• C. Assertion is correct, but Reason is incorrect.
• D. Both Assertion and Reason are incorrect.

Answer 1

The correct option is C Assertion is correct, but Reason is incorrect.

Assertion is true, but 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.
