Problem
Hydrogen and carbon dioxide gases react according to the following equation: H2(g)+CO2(g)⇌H2O(g)+CO(g) . The reaction was carried out in a sealed vessel of volume 10 dm3 . The four components of the reaction were put into the vessel in the following proportions: 2.00 mol of each of the reactants ( H2 and CO2 ) and 1.00 mol of each of the products ( H2O and CO ). The system was then allowed to come to equilibrium at 1200 K. The equilibrium constant, K , for this reaction at 1200 K is 2.10. Calculate the equilibrium concentration of each component of the reaction mixture.
