To increase the yield of H₂(g) in the water–gas reaction—the reaction of C(g) and H₂O(g) to form CO(g) and H₂(g)—a follow-up reaction called the “water–gas shift reaction” is generally used. In this reaction, some of the CO(g) of the water gas is replaced by H₂(g).

K_c = 1.00 at about 1100 K. The following amounts of substances are brought together and allowed to react at this temperature: 1.00 mol CO, 1.00 mol H₂O, 2.00 mol CO₂, and 2.00 mol H₂. Compared with their initial amounts, which of the substances will be present in a greater amount and which in a lesser amount when equilibrium is established?
