A gaseous mixture of CO and `CO_(2)` having total volume 150ml with excess of red hot charcoal to cause following reaction: `CO_(2)(g)+C(s)rarr2CO(g)` The volume increases to 250ml. Identify correct statement(s)A. Original mixture contain `(100)/(3)%` of CO.B. Original mixture contain 150 ml of `CO_(2)`.C. Original mixture contain 100ml of `CO_(2)`.D. Original mixture contain 50ml of CO,. |

Answer» `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)%` |
