1. (a) The reaction CO(g)+H2O(g)⇌H2(g)+CO2(g) was studied at 550∘C . When 4.0 moles of CO and 6.4 moles of H2O were introduced into a 1 dm3 vessel, the equilibrium mixture was found to contain 3.2 moles of both H2 and CO2 . Calculate the concentrations of CO and H2O at equilibrium and the value of K .
2. (b) At the same temperature and pressure, a different experiment was found to have 4.0 moles of both CO and H2O , and 3.0 moles of both H2 and CO2 present in the mixture after a period of reaction. Show mathematically that this mixture had not reached equilibrium, and in which direction it will react.
