Which one of the following statements is not correct?

Which plot is the adsorption isobar for chemisorption?

Which one of the following statements is not correct?

The equation which represents the Freundlich adsorption isotherm is ($x = \text{amount of gas}$, $m = \text{mass of solid}$):

For the adsorption of hydrogen on platinum,the activation energy is $30 \ kJ \ mol^{-1}$ and for the adsorption of hydrogen on nickel,the activation energy is $41.4 \ kJ \ mol^{-1}$. The logarithm of the ratio of the rates of chemisorption on equal areas of the metals at $300 \ K$ is $........$ (Nearest integer). Given: $\ln 10 = 2.3$,$R = 8.3 \ J \ K^{-1} \ mol^{-1}$.

When a dilute aqueous solution of $AgNO_3$ (in excess) is added to a solution of $KI$,the positively charged $AgI$ particles are formed due to the adsorption of which ions?
