The rate of diffusion of $SO_2$,$CO_2$,$PCl_3$ and $SO_3$ are in the following order:

Two grams of hydrogen diffuse from a container in $10 \ min$. How many grams of oxygen would diffuse through the same container in the same time under similar conditions?

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:

$CO_2$ and $N_2$ do not support combustion. However,$CO_2$ is preferred over $N_2$ for extinguishing fires because $CO_2$ .......

Explain the term 'laminar flow'. Is the velocity of molecules same in all the layers in laminar flow? Explain your answer.

At $500 \, K$ temperature in a $2 \, L$ vessel,$0.32 \, g$ of $O_2$ gas is collected over water. If the vapour pressure of water is $32 \, mbar$ at $500 \, K$,find the partial pressure of dry $O_2$ gas. $(R = 8.314 \times 10^{-2} \, L \, bar \, mol^{-1} \, K^{-1})$
