7.93. (i) Define Le Chatelier's principle. (ii) Following reactions occur in a Blast furnace. Fe2O3(s) + 3CO(g) ———–>2Fe(s) + 3CO2(g) Use Le Chatelier's principle to predict the direction of reaction when equilibrium mixture is disturbed by (a) adding Fe2O3 (b) removing CO2. (c) removing CO.

(i) Le Chatelier's principle states that the change in any factor such as temperature, pressure, concentration, etc. will cause the equilibrium to shift in such a direction so as to reduce or counteract the effect of the change. (ii) (a) On adding Fe2O3 (s), the equilibrium will remain unaffected. (b) By removing CO2 (g), the equilibrium will be shifted in the forward direction. (c) By removing CO (g), the equilibrium will be shifted in the backward direction.
