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

2.4 atm

B

8 atm

C

12atm

D

None of these

Text Solution

Verified by Experts

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