Surface Chemistry

According to Freundlich, there is an empirical relationship between the amount of gas adsorbed by a unit mass of solid adsorbent and the pressure at a given temperature:$\; \frac{x}{m} = k \cdot p^{1/n} \;\; (\; \text{ for } \; n>1)$Here, $x$ represents the mass of gas adsorbed, $m$ is the mass of the adsorbent, and $p$ is the pressure. The constants $k$ and $n$ are specific to the system being examined.By taking the logarithm of both sides of the equation, we have:$\log\; \frac{x}{m} = \log k + \frac{1}{n} \log p$To verify the validity of the Freundlich isotherm, you can plot $\log\; \frac{x}{m}$ on the y -axis and $\log p$ on the $x$-axis. If the plot forms a straight line, the isotherm is valid. If not, it indicates a lack of alignment with the Freundlich equation.
