Freundlich's adsorption isotherm (in terms of concentration) is given by the expression; $\displaystyle \frac{\mathrm{x}}{\mathrm{m}}=\mathrm{K} \cdot \mathrm{C}^{1 / \mathrm{n}}$. The possible conclusions that can be drawn from the expression are :
(A)
When $\displaystyle 1 / \mathrm{n}=1$, the adsorption is directly proportional to concentration.
(B)
When $\displaystyle 1 / \mathrm{n}=0$, the adsorption is independent of concentration.
(C)
When $\displaystyle \mathrm{n}=0$, a plot of $\displaystyle x / \mathrm{m}$ vs C is a line parallel to x -axis
(D)
When $\displaystyle \mathrm{n}=0$, a plot of $\displaystyle x / \mathrm{m}$ vs C is a curve.
