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?

Text Solution

Verified by Experts

The mixing of two gases have `Delta H` equal to zero. Therefore, it is spontaneous process because energy factor has no role to play but randomness increases i.e., randomness factor favours the process.

When two gases are mixed the entropy :-

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?
