A gaseous mixture of CO and CO_(2) having total volume 150ml with excess of red hot charcoal to causefollowingreaction: CO_(2)(g)+C(s)rarr2CO(g) The volume increases to 250ml. Identify correct statement(s)

Answer»

ORIGINAL mixture contain `(100)/(3)%` of CO.
Original mixture contain 150 ml of `CO_(2)`.
Original mixture contain 100ml of `CO_(2)`.
Original mixture contain 50ml of CO,.

Solution :`CO_(2)+C(s)rarr2CO(g)`
Vml EXCESS
`0ml` remain 2V ml
`DeltaV=2V-V=V ml=250-150=100`
`V_CO_(2))=100ml,V_(CO)=50ml`
`%"of" CO=(V_(CO))/(V_("total"))XX100=(50)/(150)xx100`
`=(100)/(3)%`
