31 A 2L vessel contains 4 g of Helium and 4 g of He
gas at 27°C. After sometime, 50% of the gas having
higher average speed is removed. What is the
percentage reduction in total pressure if temperature
remains constant?
(1) 66.67%
( 33.33%
(3) 50%
(4) 25%

Answer:
Volume of vessel=2L
He=4g
H2=4g
Total moles=2+1=3mol
T=27C=300K
P=
P=
P=36.90atm
50% of the gas having higher average speed is removed.
P=
P=24.6atm
Reduction in pressure=36.9-24.6
=12.3
Then the reduction % will be
=33.3%
option 2 is correct
