Answer

shift towards the right no change shift towards the left No change

Work Step by Step

A. Write the equilibrium constant expression. Note the solids are not included in this expression because the concentrations of solids do not change. B. Write the equilibrium constant expression. Note the solids are not included in this expression because the concentrations of solids do not change. Adding more Fe will have no effect on the equilibrium constant because Fe is a solid and does not appear in the equilibrium constant expression. C. Write the equilibrium constant expression. Note the solids are not included in this expression because the concentrations of solids do not change. D. Write the equilibrium constant expression. Note the solids are not included in this expression because the concentrations of solids do not change. Adding a catalyst will have no effect on the equilibrium constant because a catalyst does not appear in the equilibrium constant expression. A catalyst only serves to speed up a reaction.
