Select the correct statement.

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?

Which of the following conditions is favorable for $Van \ der \ Waals$ adsorption?

Given below are two statements: One is labelled as Assertion $A$ and the other is labelled as Reason $R$.
Assertion $A:$ Amongst $He$,$Ne$,$Ar$ and $Kr$; $1 \ g$ of activated charcoal adsorbs more of $Kr$.
Reason $R$: The critical volume $V_c \left( cm^3 \ mol^{-1} \right)$ and critical pressure $P_c \left( atm \right)$ is highest for Krypton but the compressibility factor at critical point $Z_c$ is lowest for Krypton.
In the light of the above statements,choose the correct answer from the options given below.

The rate of physical adsorption:

In the figure,a straight line is given for the Freundlich Adsorption isotherm equation $(y = mx + c)$,where the equation is $y = 0.3x + 0.7033$. The values of $\frac{1}{n}$ and $\log K$ are respectively:
