What concentration of `CO_(2)` be in equilibrium with `0.025 M` CO at `120^(@)C` for the reaction `FeO(s)+CO(g) hArr Fe(s)+CO_(2)(g)` if the value of `K_(c)=5.0` ?A. `0.125 M`B. `0.0125 M`C. `1.25 M`D. `12.5 M` |
Answer» Correct Answer - A `{:(,FeO(s),+,CO(g),hArr,Fe(s),+,CO_(2)(g)),("At eq.",-,,0.025,,-,,x),(,"solid",,,,"solid",,):}` `K_(c)=[(CO_(2)(g))/(CO(g))]=x/0.025=5.0` (Given) `:. x=0.125 M` `[CO_(2)]=0.125 M` |
