For the adsorption of a solution on a solid surface,the Freundlich adsorption isotherm is given by $\frac{x}{m} = k C^{1/n}$. The plot of $\log (\frac{x}{m})$ versus $\log C$ is shown below. This corresponds to which of the following conditions?

Which of the following is true with respect to chemical adsorption?

The given graphs $I$,$II$,$III$,and $IV$ represent general trends observed for different physisorption and chemisorption processes under mild conditions of temperature and pressure. Which of the following choice$(s)$ about $I$,$II$,$III$,and $IV$ is (are) correct?
$(A)$ $I$ is physisorption and $II$ is chemisorption
$(B)$ $I$ is physisorption and $III$ is chemisorption
$(C)$ $IV$ is chemisorption and $II$ is chemisorption
$(D)$ $IV$ is chemisorption and $III$ is chemisorption

In the Freundlich adsorption isotherm equation $(x/m) = kp^{1/n}$,the value of $n$ is:
