Answer & Solution

Correct Answer

(A) \(\log \frac{x}{m}\) on \(y\)-axis and \(\log \mathrm{p}\) on \(x\)-axis

Step-by-step Solution

Detailed explanation

Freundlich adsorption isotherm is an empirical relationship between quantity of gas adsorbed by unit mass of solid adsorbent and pressure at a particular temperature. \(\frac{\mathrm{x}}{\mathrm{m}}=\mathrm{K} \cdot \mathrm{p}^{1 / \mathrm{n}}(\mathrm{n}\gt1)\) Taking logarithm.…
