If $N_2, O_2, H_2$,and $He$ gases are filled separately in four car tubes at the same pressure,which gas will diffuse first?

Pressure exerted by saturated water vapour is called aqueous tension. What correction term will you apply to the total pressure to obtain the pressure of dry gas?

The total pressure of a mixture of two gases is equal to .......

The rate of diffusion of $SO_{2}$,$CO_{2}$,$PCl_{3}$ and $SO_{3}$ are in the following order:

Write four main properties of gases.

$A$ mixture of $0.5 \text{ mol}$ $N_2$ gas, $1.0 \text{ mol}$ $O_2$ gas and $1.5 \text{ mol}$ $H_2$ gas exerts a total pressure of $18 \text{ bar}$. Find the partial pressure of $O_2(g)$. (in $\text{ bar}$)
