Question

A closed vessel contains He and
03 at a
pressure of P atm. The ratio of He
and O atoms
is 1:1. If He is removed from the
vessel, the
pressure of the system will reduce
to
0.5 P.
0.75 P.
0.25 P.
0.33 P​

Answer 1

Answer:

0.5 P

Explanation:

He and O3 has equal number of molecules

So, mole fraction is also equal of each component

Partial pressure=   1/2  of total pressure

So, when we remove the He the partial pressure of He is removed.

So, P goes to P/2⇒0.5Patm
