The validity of Freundlich isotherm can be verified by plotting

The validity of Freundlich isotherm can be verified by plotting
  1. $\log \frac{x}{m}$ on $y$-axis and $\log \mathrm{p}$ on $x$-axis
  2. $\frac{x}{m}$ on $Y$-axis and $p$ on $x$-axis
  3. $\log \frac{x}{m}$ on $x$-axis and p on $y$-axis
  4. $\frac{x}{m}$ on $x$-axis and $\log \mathrm{p}$ on $y$-axis

Solution

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. $\begin{aligned} & \log \frac{x}{m}=\log K+\frac{1}{n} \log p \\ & y=c+m x\end{aligned}$ on y -axis $=\log \frac{\mathrm{x}}{\mathrm{m}}$ on x -axis $=\log \mathrm{p}$
