Answer:

PCl

5

⇋PCl

3

+Cl

2

Initial conc.(M) 0.1 0 0

At eq. 0.1−x x x

The expression for the equilibrium constant is:

K

c

=

[PCl

5

]

[PCl

3

][Cl

2

]

=

0.1−x

x×x

=13.7

Hence, x=0.0993

Total number of moles =n=10(0.1+x)=10(0.1+0.0993)=1.993

P=

V

nRT

=

10

1.993×0.0821×546

P=8.93

100P=893
