When the molar concentrations of SO(2), ...

When the molar concentrations of `SO_(2), O_(2) and SO_(3)` at equilbrium at certain temperature are `0.5 , 0.25 ` & 0.25 M respectively, `k_(c) ` for `2SO_(3) hArr 2SO_(2) + O_(2)` is

A

`0.5 lit mol^(-1)`

B

`1 lit^(2)-mol^(-2)`

C

`1 mol-lit^(-1)`

D

`0.25 mol^(2)-lit^(-2)`

Text Solution

Verified by Experts

The correct Answer is:
C
`2SO_(3(g)) harr 2SO_(2(g)) +O_(2(g))`
`K_(c)=([SO_(2)]^(2)[O_(2)])/([SO_(3)]^(2))`
