Two vessels divided by a partition contain one mole of `N_(2)` and two moles of `O_(2)` gas. If the partition is removed and gases mixed isothermally, Find the change in entropy due to mixing assuming initial and final pressure are same.

Using `Delta S_("system (mixing g)") = -R sum n_(i)ln chi_(i)`
`=-R(1xxln((1)/(3))+2xxln((2)/(3)))`
`=R(ln 3+2ln((3)/(2)))=8.314(1.1+2xx0.4)=15.8 JK^(-1)`

Two vessels divided by a partition cotain one mole of N_(2) and two moles of O_(2) gas. If the partition is removed and gases mixed isothermally, find the change in entrope due to mixing assuming initial and final pressure are same.

As isolated box, equally partitioned contains two ideal gases A and B as shown What the partition is removed, the gases mix. The changes in enthalpy ( Delta H) and entropy ( Delta S) in the process, respectively, are

1 mole of sample of O_2 and 3 mole sample of H_2 are mixed isothermally in a 125.3 litre container at 125^@C the total pressure of gaseous mixture will be

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?

One mole of a monatomic gas and one mole of a diatomic gas are initially in the same state. Both gases are expanded isothermally and then adiabatically such that they acquire the same final state. Choose the correct statement.

A container is divided into two chambers by a partition. The volume of first chamber is 4.5 litre and second chamber is 5.5 litre. The first chamber contain 3.0 moles of gas at pressure 2.0 atm and second chamber contain 4.0 moles of gas at pressure 3.0 atm. After the partition is removed and the mixture attains equilibrium, then, the common equilibrium pressure existing in the mixture is "x"xx10^(-1) atm. Value of x is "___" .

A vessel contains 0.1 mol e of He, 0.1 mole of O_(2) and 0.3 mole of N_(2) . The total pressure is 1 atomosphere. The pressure exerted by O_(2) is

An insulated cylindrical vessel is divided into three identical parts by two partitions 1 and 2. The left part contains O_(2) gas, the middle part has N_(2) and the third chamber has vacuum. The average molecular speed in oxygen chamber is V_(0) and that in nitrogen chamber is sqrt((8)/(7)) V_(0) . Pressure of the gases in two chambers is same. Partition 1 is removed and the gases are allowed to mix. Now the stopper holding the partition 2 is removed and it slides to the right wall of the container, so that the mixture of gases occupy the entire volume of the container. Find the average speed of O_(2) molecules now.

If 1 mole of H_(2) , 2 moles of O_(2) and 3 moles of N_(2) are mixed in a vessel and total pressure was found to be 12 atm then the partial pressure exerted by N_(2) in the vessel will be
