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

Answer»

`0.36`
`0.45`
`0.54`
`0.675`

SOLUTION :`{:(,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`
