A rigid and insulated tank of `3m^(3)` volume is divided into two compartments. One compartment of volume of `2m^(3)` contains an ideal gas at `0.8314` Mpa and 400 K while the second compartment of volume of `1m^(3)` contains the same gas at `8.314` Mpa and 500 K. If the partition between the two compartments is rptured, the final temperature of the gas is :

A

420K

B

450K

C

480K

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
C
Given
`4H(g)to2H_(2)(g),DeltaH=-869.6kJ`
or `2H_(2)(g)to4H(g), DeltaH=869.6kJ`
`H_(2)(g)to2H(g),DeltaH=869.9/2=434.8kJ`

A container of volume 1m^(3) is divided into two equal compartments by a partition. One of these compartments contains an ideal gas at 300 K . The other compartment is vacuum. The whole system is thermally isolated from its surroundings. The partition is removed and the gas expands to occupy the whole volume of the container. Its temperature now would be

A container is divided into two compartments. One compartment contains 2 moles of N_(2) gas at 1 atm and 300 K and other compartment contains H_(2) gas at the same temperature and pressure. Volume of H_(2) compartment is four times the volume of N_(2) compartment [Assuming no reaction under these conditions] Calculate the final total pressure if partition between two compartments is removed.

A container of volume 2L is seperated into equal compartments. In one compartment, one mole of an ideal monoatomic gas is filled at 1 bar pressure and the other compartment is completely evacuted. A pihole is made in the seperator so gas expands to occupy full 2 L and heat is supplied to gas so that finally pressure of gas equals 1 bar. Then :

An insulated container of gas has two chambers separated by an insulating partition. One of the chmabers has volume V_1 and contains ideal gas at pressure P_1 and temperature T_1 .The other chamber has volume V_2 and contains ideal gas at pressure P_2 and temperature T_2 . If the partition is removed without doing any work on the gas, the final equilibrium temperature of the gas in the container will be

A container is divided into two compartments. One compartment contains 2 moles of N_(2) gas at 1 atm and 300 K and other compartment contains H_(2) gas at the same temperature and pressure. Volume of H_(2) compartment is four times the volume of N_(2) compartment [Assuming no reaction under these conditions] If the container containing N_(2) and H_(2) are further heated to 1000 K, forming NH_(3) with 100% yeild calculate the final total pressure.

In Fig., a container is shown to have a movable (without friction) piston on top. The container and the piston are all made of perfectly insulating material allowing no heat transfer between outside and inside the container. The container is divided into two compartments by a rigid partition made of a thermally conducting material that allows slow transfer of heat. the lower compartment of the container is filled with 2 moles of an ideal monoatomic gas at 700 K and the upper compartment is filled with 2 moles of an ideal diatomic gas at 400 K. the heat capacities per mole of an ideal monoatomic gas are C_(upsilon) = (3)/(2) R and C_(P) = (5)/(2) R , and those for an ideal diatomic gas are C_(upsilone) = (5)/(2) R and C_(P) = (7)/(2) R. Now consider the partition to be free to move without friction so that the pressure of gases in both compartments is the same. the total work done by the gases till the time they achieve equilibrium will be
