Two closed vessel A and B of equal volume of 8.21 L are connected by a narrow tube of negligible volume with open valve. The left hand side container is found to contain 3 mole `CO_(2)` and 2 mole of He at 400 K. What is the partial pressure of He in vessel B at 400 K?

A

2.4atm

B

8atm

C

12atm

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B
`P_(1)=(5xxRT)/V`, Partial pressure of He=`2/5xx((5RT)/V)`
`=(2xx0.0821xx400)/(8.21)=8atm`

Two flasks A and B of equal volume containing NH_(3) and HCl gases, are connected by a narrow tube of negligible volume. The two gases were prevented from mixing by stopper fitted in connecting tube. For further details of the experiment, refer to the given figure. What will be final pressure (in mm of Hf) in each flask when passage connecting two tubes are opened, assuming ideal gas behaviour of NH_(3) and HCl gas and the reaction NH_(3)(g)+HCl(g)rarrNH_(4)Cl(s) goes to completion.

Two flasks of equal volume are connected by a narrow tube ( of negligible voume ) all at 27^(@)C and contain 0.70 mole of H_(2) at 0.5 atm. One of the flask is then immersed into a bath kept at 127^(@)C , while the other remainsat 27^(@)C . The final pressure in each flask is :

Two vessels A and B of equal volume (V_0) are connected by a narrow tube which can be closed by a value. The vessels are fitted with piston which can be moved to change the volumes. Initially, the valve is open and the vessels contain an ideal gas (C_p / C_v = gamma ) at atomspheric pressures (P_0) and atmoshpeheric temperature (T_0) . The walls of the vessels A are diathermic and those of B are adiabatic. The value is now closed and the pistons are slowly pulled out to increase the volumes of the of the vessels to dobuled the original value.(a) Find the temperatures and pressures in the two vessels. (b) The value is now opened for sufficeint time so that the gases acquire a common tempertures and pressures . Find the new values of the temperatuere and the pressures.
