$CO_{2}$ gas adsorbs on charcoal following Freundlich adsorption isotherm. For a given amount of charcoal,the mass of $CO_{2}$ adsorbed becomes $64$ times when the pressure of $CO_{2}$ is doubled. The value of $n$ in the Freundlich isotherm equation is $......\,\times 10^{-2}$. (Round off to the Nearest Integer)

Among the following,the number of curves not in accordance with the Freundlich adsorption isotherm is:

The charge on colloidal particles is due to

When $\left( \frac{m}{x} \right)$ is plotted against $\frac{1}{p}$ for the equation $\frac{x}{m} = \frac{ap}{1 + bp}$,we get a straight line. What are the slope and intercept of this line?

For the adsorption of a gas on a solid adsorbent,which of the following is positive?

Given below are two statements. One is labelled as Assertion $A$ and the other is labelled as Reason $R$.
Assertion $A :$ Activated charcoal adsorbs $SO_{2}$ more efficiently than $CH_{4}$.
Reason $R$ : Gases with lower critical temperatures are readily adsorbed by activated charcoal.
In the light of the above statements,choose the correct answer from the options given below.
