Synthesis gas (a mixture of CO and H2) is increased in concentration of hydrogen by passing it with steam over a catalyst. This is the so-called water–gas shift reaction. Some of the CO is converted to CO2, which can be removed:
CO(g) + H2O(g) ⇄ CO2(g) + H2(g)
Suppose you start with a gaseous mixture containing 1.00 mol CO and 1.00 mol H2O.
When equilibrium is reached at 1000°C, the mixture contains 0.43 mol H2. What is the
molar composition of the equilibrium mixture?
