Question

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.

• A. If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
• B. If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
• C. If the Assertion is correct but Reason is incorrect.
• D. If the Assertion is incorrect and Reason is correct.

Answer 1

Answer: (C)

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.
