2 moles each of `SO_(3)`, CO, `SO_(2)` and `CO_(2)` is taken in a 1 L vessel. If `K_(C)` for `SO_(3) + COhArrSO_(2) + CO_(2)` is `1//9` then:

Options

A. total no. of moles at equilibrium are less than 8
B. `n(SO_(3)) + n(CO_(2))=4`
C. `[n(SO_(2))//n(CO)]lt 1`
D. both (b) and (c).

Answer

D

Explanation

`{:(,SO_(3),+CO,hArr,SO_(2),+,CO_(2)),(t=0,2M,2M,,2M,,2M),(t=oo,2+x,2+x,,2-x,,2-x):}`
