Hydrogen Gas Reacts with Iron(III) Oxide and Produces Iron Metal $\rightarrow$

Hydrogen gas reacts with iron(III) oxide and produces iron metal which can be used to produce steel according to the reaction below. Choose the response that is incorrect concerning the equilibrium system.
Fe₂O₃ (s) + H₂ (g) + heat $\rightarrow$ 2 Fe (s) + 3 H₂O (g)

A) Lowering the reaction temperature will increase the concentration of hydrogen gas.
B) Increasing the pressure on the reaction chamber favors the formation of products.
C) Continually removing water from the reaction chamber increases the yield of iron.
D) Decreasing the volume of hydrogen gas will reduce the yield of iron.
