Sodium hydrogen carbonate decomposes above 110 degree C to form sodium carbonate, water, and carbon dioxide. 2NaHCO_3(s) Na_2CO_3(s) + H_2O(g) + CO_2(g) One thousand grams of sodium hydrogen carbonate are added to a reaction vessel, the temperature is increased to 200 degree C, and the system comes to equilibrium. What happens in this system if another 50 g of sodium carbonate are now added? The partial pressure of carbon dioxide will increase. The partial pressure of carbon dioxide will decrease. The partial pressure of carbon dioxide will be unchanged. The amounts of all products will be greater when equilibrium is reestablished. None of these conclusions is justified without knowing the equilibrium constant.
