Following reaction occurs in a Blast Furnace: \[F{{e}_{2}}{{O}_{3}}(s)+3CO(g)\rightleftharpoons 2Fe(l)+3C{{O}_{2}}(g)\] Use Le Chatelier's principle to predict the direction of reaction when equilibrium mixture is disturbed by (a) adding \[F{{e}_{2}}{{O}_{3}}\]  (b) removing \[C{{O}_{2}}\]  (c) removing CO.

Answer:

                (a) On adding \[F{{e}_{2}}{{O}_{3}}\,(s)\], the equilibrium will remain unaffected. (b) By removing \[C{{O}_{2}}(g)\], the equilibrium will be shifted in the forward direction (c) By removing \[CO(g)\], the equilibrium will be shifted in the backward direction.
