Vedclass · Answer

(A) The Freundlich adsorption isotherm is an empirical relationship between the quantity of gas adsorbed by a unit mass of solid adsorbent and the pressure at a particular temperature.$\frac{x}{m} = K \cdot p^{1/n}$ (where $n > 1$)Taking the logarithm on both sides:$\log \frac{x}{m} = \log K + \frac{1}{n} \log p$This equation follows the linear form $y = mx + c$,where:$y = \log \frac{x}{m}$ (plotted on the $y$-axis)$x = \log p$ (plotted on the $x$-axis)$m = \frac{1}{n}$ (slope)$c = \log K$ (intercept)Therefore,plotting $\log \frac{x}{m}$ on the $y$-axis and $\log p$ on the $x$-axis yields a straight line,verifying the isotherm.

The validity of the Freundlich isotherm can be verified by plotting:
