One mole of SO(3) was placed in a vessel...

One mole of `SO_(3)` was placed in a vessel of 1 litre capacity at a certain temperature when the following equilibrium was established.
`2SO_(3)iff2SO_(2)+O_(2)`
At equilibrium, 0.6 moles of `SO_(2)` were formed. The equilibrium constant of the reaction will be

A

`0.36`

B

`0.45`

C

`0.54`

D

`0.675`

Text Solution

Verified by Experts

The correct Answer is:
D
`{:(,2SO_(3),iff,2SO_(2),+,O_(2)),("Initial","1 mole",,0,,0),("At eqm.",1-0.6=0.4,,0.6,,0.3):}`
`K=((0.6)^(2)(0.3))/((0.4)^(2))=0.675`
