Concerning the following reaction at equilibrium:

Question

3Fe(s) + 4H2O(g) Fe3O4(s) + 4H2(g), increasing the concentration of the Fe(s) would:
Answer A. Shift the equilibrium to the right
B. Shift the equilibrium to the left
C. No change
D. Increase the value of the equilibrium constant, K
E. Decrease the value of the equilibrium constant, K

Answer 1

What do you not understand about Le Chatelier's Principle? It says that a reaction in equilibrium will shift to undo what we do to it. Hint for this question: Remember solids and pure liquids are not included in equilibrium constants.
