The rate of diffusion of a gas is inversely proportional to

The time for complete evaporation depends on which factors? Explain.

Which of the following is true for the gaseous state?

$A$ gaseous mixture of $2$ moles of $A$, $3$ moles of $B$, $5$ moles of $C$, and $10$ moles of $D$ is contained in a vessel. Assuming that gases are ideal and the partial pressure of $C$ is $1.5 \ atm$, what is the total pressure (in $atm$)?

In a closed container,the number of oxygen and hydrogen molecules are equal at a pressure of $740 \, mm$. If oxygen is removed from the system,the pressure will be:

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