Consider the following equilibrium system: 2SO2 + O2 --> 2SO3 Into a 2.00 Liter container, 0.500 mol of SO3, was placed and heated to 300°C. After equilibrium was established, the container was found to have 0.300 moles of SO3 present along with the other gases. Calculate the equilibrium concentration of each molecule and the equilibrium constant for this reaction at this temperature.

True/False. Explain your answer in one sentence or less.   In an equilibrium process, the concentrations of products and of reactants are equal. The value of the equilibrium constant for a given reaction depends on the initial concentrations of reactants. Large value for equilibrium constant K means the reaction will be less complete at the equilibrium point. The concentration of a pure solid is left out of an equilibrium constant expression but a pure liquid is included.

Consider the following reaction at equilibrium. What effect will removing some SO2 have on the system? SO2(g) + NO2(g) = SO3(g) + NO(g) The pressure of SO3 will increase The equilibrium constant will decrease. No change will occur since SO2 is not included in the equilibrium expression. The pressure of NO2 will increase. The reaction will shift to decrease the pressure.
