Given that DeltaH = 0 for mixing of two gases.Explain whether the diffusion of these gases into each other in a closed container is a spontaneous process or not?

Mixing of two gases by diffusion is

Two gases cannot diffuse into each other.

The molecules in gases frequently collide with each other and the sides of the container in which they are kept.

Molecular weights of two gases are 64 annd 100 respectively. If rate of diffusion of first gas be 15 mL*sec^(-1) , then what is the rate of diffusion of the other?

A vessel is divided by a solid partition into two parts of equal volume. One part is filled with nitrogen and the other with carbon monoxide. It may be assumed that the cross-sect.ional areas of the molecules of the two gases are the same. The relative molecular masses of hoth gases are also the same (equal to 28). Finally, the pressures in both parts are the same. After the partition is lifted, the gases begin to diffuse into each other. flow does the amount of each gas that has transferred to the part occupied by the other gas depend on the initial pressures of the gases?

Name two gases other than carbondioxide that are given out during burning of fossil fuel and contribute towards acid rain.

(a) What is meant by 'diffusion' ? Give one example of diffusion in gases. (b) Why do gases diffuse very fast ? (c ) Name two gases of air which dissolve in water by diffusion. What is the importance of this process in nature ?

Non reacting gases have a tendency to mix with each other. This property is known is :
