The interaction energy of $London$ forces between two particles is proportional to $r^{x}$,where $r$ is the distance between the particles. The value of $x$ is:

The ratio of rates of diffusion of gases $A$ and $B$ is $1 : 0.707$. If the molecular weight of $B$ is $32$,the molecular weight of $A$ is

Which of the following mixtures of gases does not obey Dalton's law of partial pressure?

In a container,the mole ratio of two gases $A$ and $B$ is $2 : 5$. The total pressure of the container is $3.5 \times 10^5 \ Pa$. If all molecules of $A$ are removed from the container,what will be the pressure exerted by the molecules of $B$?

When $0.0168 \ mol$ of $O_2$ obtained from the decomposition of $KClO_3$ is collected over water at $25 \ ^oC$,the volume is $428 \ mL$ and the total pressure is $754 \ mm$. What is the aqueous tension (water vapor pressure) at $25 \ ^oC$ in $mm$?
